Application Process

1
Identify the Right Role on Apex's Greenhouse-Powered Careers Page
Navigate to Apex Companies' careers page, which is hosted through Greenhouse. With 150+ open openings spanning environmental remediation, industrial hygiene, stormwater, wastewater, and construction management, take time to filter by discipline, location, and seniority level. Pay close attention to whether a role is field-based, office-based, or hybrid, as Apex positions vary significantly in their on-site requirements.
2
Prepare Your Tailored Resume and Supporting Documents
Before clicking 'Apply,' customize your resume to mirror the specific language used in the Apex job posting — including technical certifications (e.g., PE, PG, CIH, 40-hour HAZWOPER), regulatory frameworks (CERCLA, RCRA, NPDES), and project types (remediation, PRP, Phase I/II ESAs). Apex roles span multiple disciplines, so your resume should clearly signal which environmental specialty you bring. Prepare any additional documents the posting requests, such as a cover letter or writing sample.
3
Complete the Greenhouse Application Form Thoroughly
Greenhouse will present a structured application form that may include custom screening questions specific to the Apex role — such as your willingness to travel, relevant certifications, or years of experience in remediation or industrial hygiene. Answer every question completely, as hiring managers at environmental firms commonly use these screening responses to prioritize candidates before reviewing resumes. Incomplete applications may be filtered out early.
4
Initial Screening by Recruiting or HR Team
After submission, an Apex recruiter or HR coordinator will typically review your application, focusing on your environmental credentials, relevant project experience, and geographic fit. Given the specialized nature of Apex's work, they're specifically evaluating whether your technical qualifications align with the role's regulatory and field requirements. This screening stage commonly takes one to three weeks, depending on role urgency.
5
Phone or Video Interview with Recruiter or Hiring Manager
Candidates who pass initial screening are typically invited to a phone or video interview. For Apex, this conversation often centers on your specific project history — expect questions about remediation sites you've managed, regulatory agencies you've interfaced with, or field challenges you've navigated. This is also where Apex evaluates your communication skills, which are critical for client-facing environmental consulting roles.
6
Technical or Panel Interview with Project Leaders
Advancing candidates commonly participate in a more in-depth interview, often with a senior project manager, department head, or regional director. For technical roles like Environmental Principal or Industrial Hygienist, expect scenario-based questions about regulatory compliance strategies, project budgeting, or field safety protocols. For project management roles, you may be asked to walk through how you've managed scope, schedule, and client relationships on complex environmental projects.
7
Offer, Background Check, and Onboarding
Successful candidates receive a formal offer through Greenhouse, which may include details on compensation, benefits, and start date. Given the nature of environmental field work, Apex commonly conducts background checks and may verify certifications (OSHA training, professional licenses). Onboarding typically includes safety orientation and project team introductions, reflecting the company's emphasis on field safety and collaborative project delivery.

Resume Tips for Apex Companies

critical

Lead with Environmental Certifications and Licenses

Apex roles frequently require or prefer specific credentials — 40-hour HAZWOPER, PE (Professional Engineer), PG (Professional Geologist), CIH (Certified Industrial Hygienist), CHMM, or LSRP, depending on the discipline. Place these in a dedicated 'Certifications' section near the top of your resume and repeat them in context within your experience bullets. Greenhouse's parsing will pick up these terms, and Apex recruiters scanning dozens of applications will immediately see your qualifications. If you hold state-specific licenses relevant to the job's location, highlight those explicitly.

critical

Mirror Apex's Regulatory and Technical Language

Environmental consulting has a dense vocabulary, and Apex job postings are no exception. If a posting mentions CERCLA, RCRA, TSCA, NPDES permits, Phase I/II ESAs, risk assessments, or remedial investigation/feasibility studies (RI/FS), use those exact terms in your resume. Greenhouse's keyword matching and recruiter searches depend on precise terminology. Avoid abbreviating terms unless you've also spelled them out — for instance, write 'Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA)' at first mention to ensure both the acronym and full phrase are captured.

critical

Quantify Project Scope, Budgets, and Outcomes

Apex hires across all levels of project management, from Assistant Project Manager to Environmental Principal. Demonstrate your impact by quantifying: 'Managed $2.4M remediation project across 3 sites,' 'Oversaw team of 8 field technicians during soil and groundwater investigation,' or 'Reduced project timeline by 15% through optimized sampling strategy.' Environmental consulting is fundamentally a project-delivery business, so showing that you can manage scope, budget, and schedule is more persuasive than listing responsibilities. Principals and senior managers should include business development metrics like proposal win rates or client retention.

recommended

Highlight Client and Regulatory Agency Interaction

Environmental consultants at Apex regularly interface with clients (developers, industrial operators, government agencies) and regulators (EPA, state DEQs, local health departments). Your resume should demonstrate this experience explicitly — for example, 'Presented remedial action plan to NJDEP and negotiated compliance timeline' or 'Served as primary client contact for Fortune 500 industrial client across 12 remediation sites.' This signals readiness for the client-facing aspects of Apex's consulting model, which is often the differentiator between mid-level and senior candidates.

recommended

Showcase Field Experience and Safety Awareness

Many Apex positions involve significant fieldwork — remediation oversight, industrial hygiene sampling, stormwater inspections, or construction monitoring. Highlight your field competencies: equipment you've operated or overseen, field safety programs you've developed or followed, and your comfort working on active construction or industrial sites. Mentioning OSHA 10/30-hour training, confined space entry, or site-specific health and safety plan (HASP) development demonstrates your alignment with Apex's safety-first operational culture.

recommended

Use Clean, ATS-Friendly Formatting for Greenhouse

Greenhouse parses resumes reliably, but you should still avoid tables, text boxes, headers/footers with critical information, and graphics that could disrupt parsing. Use standard section headings: 'Professional Experience,' 'Education,' 'Certifications,' and 'Technical Skills.' Stick to PDF or Word format, with a clean single-column layout. Environmental resumes often benefit from a brief 'Technical Skills' section listing software (AutoCAD, ArcGIS, EnviroData, EQuIS) and field instruments (PID, XRF, groundwater sampling equipment) — these terms are highly searchable.

recommended

Tailor Your Resume to the Specific Apex Discipline

Apex's 200+ openings span distinct disciplines — remediation, industrial hygiene, stormwater, wastewater, and construction. Don't submit a generic environmental resume. If you're applying for a remediation role, emphasize site characterization, contaminant fate and transport, and remedial system design. For industrial hygiene, highlight exposure assessments, asbestos/lead surveys, and OSHA compliance. For stormwater, focus on SWPPP development, MS4 permitting, and BMP design. Greenhouse allows recruiters to search by keywords within applications, so discipline-specific terminology matters enormously.

Include Relevant Software and Data Management Tools

Modern environmental consulting relies heavily on data management and visualization tools. Apex professionals commonly use platforms like EQuIS, Enviro.Data, GIS software (ArcGIS/QGIS), AutoCAD, and project management tools (Primavera P6 for construction scheduling roles, Microsoft Project). Including these in a 'Technical Proficiencies' section gives you a keyword advantage in Greenhouse searches and signals to hiring managers that you can integrate into Apex's existing technology workflows without an extended learning curve.

ATS System: Greenhouse

Greenhouse is a structured hiring platform that Apex Companies uses to manage applications from submission through offer. It parses uploaded resumes to extract key information, enables recruiters to search candidates by keywords and qualifications, and supports custom screening questions tailored to each role's requirements.

Submit your resume in PDF or Word format — Greenhouse handles both well, but avoid image-based PDFs that can't be parsed for text
Use exact keywords from the Apex job posting, especially certifications (HAZWOPER, PE, CIH), regulations (CERCLA, RCRA), and technical processes (remedial design, Phase II ESA)
Complete all custom screening questions thoroughly — Apex commonly uses these to filter candidates on certifications, travel willingness, and years of relevant experience
Keep your resume formatting simple with standard section headers — avoid tables, columns, or graphics that may disrupt Greenhouse's resume parsing
Spell out acronyms at least once alongside the abbreviation (e.g., 'National Pollutant Discharge Elimination System (NPDES)') to match both search patterns
Apply to specific roles rather than submitting the same resume to multiple unrelated positions — Greenhouse tracks all your applications, and recruiters can see your submission history
If Apex's application includes an optional cover letter field, use it — Greenhouse stores this alongside your resume and it gives you space to explain career transitions or relocation plans

Interview Culture

Interviewing at Apex Companies typically reflects the practical, project-oriented nature of environmental consulting.

The process commonly involves two to three rounds, progressing from a recruiter screen to technical interviews with the people you'd actually work alongside — project managers, department directors, and sometimes regional leadership. The initial phone screen usually lasts 20 to 30 minutes and covers your background, geographic flexibility, certifications, and interest in the specific role. Apex operates across many offices and project sites, so expect questions about your willingness to travel or relocate, particularly for field-heavy roles in remediation, industrial hygiene, or construction management. The technical interview is where Apex digs into your professional expertise. For Environmental Project Managers and Principals, expect detailed discussions about projects you've led — how you managed budgets, navigated regulatory hurdles, handled unexpected field conditions, and communicated with clients and agencies. You may be asked scenario-based questions such as how you'd approach a newly discovered contaminant during a remediation project, or how you'd prioritize competing deadlines across a PRP program. For Industrial Hygienists, questions commonly focus on exposure assessment methodology, OSHA standards, and report writing. Construction Schedulers should be prepared to discuss Primavera P6 or similar tools and demonstrate their approach to critical path analysis. Culture fit matters at Apex. Interviewers are commonly assessing whether you can collaborate across disciplines — a remediation PM might need to coordinate with industrial hygienists, stormwater specialists, and construction teams on a single project. Demonstrating flexibility, strong communication skills, and a team-first mentality resonates well. Apex's culture values professionals who are both technically competent and client-ready, meaning you can explain complex environmental concepts to non-technical stakeholders. Come prepared with specific project examples that showcase problem-solving, regulatory knowledge, and leadership. Ask thoughtful questions about the team structure, project pipeline, and growth opportunities within the office or practice area you'd join. Following up with a thank-you email that references a specific topic from the interview demonstrates the professionalism and attention to detail Apex values.

Frequently Asked Questions

How long does the Apex Companies hiring process typically take?

Based on patterns common in environmental consulting firms of Apex's size, the hiring process typically takes three to six weeks from application to offer, though this can vary based on role urgency and seniority. Field-level and technician positions may move faster, sometimes within two to three weeks, while senior roles like Environmental Principal may involve additional interview rounds and take longer. Keep an eye on your email (including spam folders) for Greenhouse notifications, and don't hesitate to follow up with your recruiter contact if you haven't heard back within two weeks of an interview.

Does Apex Companies require a cover letter with my application?

While not always explicitly required, submitting a cover letter through Greenhouse is strongly recommended for Apex applications, especially if you're transitioning between environmental disciplines, relocating, or applying for a senior-level role. Use the cover letter to connect your specific project experience to the role's requirements — for example, explain how your remediation work at contaminated industrial sites prepares you for Apex's PRP program projects. A well-crafted cover letter also demonstrates the written communication skills that are essential in a consulting environment where technical reports and client correspondence are daily deliverables.

What format should my resume be in when applying through Apex's Greenhouse system?

Submit your resume as a PDF or Word document (.docx). Greenhouse parses both formats effectively, but ensure your PDF is text-based (not a scanned image). Use a single-column layout with standard section headings like 'Professional Experience,' 'Education,' 'Certifications,' and 'Technical Skills.' Avoid tables, text boxes, or multi-column designs that can cause parsing errors. For environmental professionals, two to three pages is acceptable given the importance of detailing project-specific experience, certifications, and technical competencies.

What certifications does Apex Companies look for in candidates?

The specific certifications depend heavily on the role and discipline. For remediation and site assessment roles, 40-hour HAZWOPER training with current 8-hour refresher is frequently listed as required, along with Professional Engineer (PE) or Professional Geologist (PG) licenses for mid-to-senior level positions. Industrial Hygiene roles commonly require or prefer Certified Industrial Hygienist (CIH) designation and OSHA 30-hour training. Construction-focused roles may value PMP or similar project management certifications. State-specific licenses — such as Licensed Site Remediation Professional (LSRP) in New Jersey — can be significant differentiators depending on the office location. Always check the specific job posting for required versus preferred certifications.

Can I apply to multiple Apex Companies positions at the same time?

Yes, Greenhouse allows you to apply to multiple Apex positions, and if your skills span different disciplines (for instance, if you have both remediation and industrial hygiene experience), applying to relevant roles in each area is reasonable. However, avoid applying indiscriminately to every open position — Greenhouse tracks all your applications, and recruiters can see your full submission history. Applying to ten unrelated roles signals a lack of focus. Instead, target two to four positions that genuinely match your qualifications, and tailor your resume for each one to reflect the specific discipline's terminology and requirements.

Does Apex Companies offer remote work options?

The nature of environmental consulting means that many Apex roles involve significant field work — site visits, sampling, construction oversight, inspections — which cannot be performed remotely. However, some positions with heavier office-based components (data analysis, report writing, project management, construction scheduling) may offer hybrid arrangements. Each job posting on Greenhouse typically indicates the work location and any flexibility. During the interview process, ask directly about the role's field-to-office ratio and any remote work policies specific to that office or service line, as practices may vary across Apex's geographic footprint.

I'm a recent graduate with limited experience. Can I still apply to Apex Companies?

Absolutely. Apex posts roles at various experience levels, including entry-level positions like Landscape Technician, field staff, and Assistant Project Manager roles. If you're a recent graduate with a degree in environmental science, geology, environmental engineering, civil engineering, or industrial hygiene, focus on relevant internships, academic projects, and any field experience you've gained. Highlight your OSHA training, familiarity with field equipment, and coursework in relevant regulatory frameworks. Your cover letter should express genuine interest in the specific environmental discipline and a willingness to learn in a project-based consulting environment. Entry-level candidates who demonstrate strong foundational knowledge and field readiness often stand out.

How should I prepare for a technical interview at Apex Companies?

Prepare two to three detailed project narratives that you can adapt to different interview questions. Each narrative should cover the project scope, your specific role, the technical challenges you encountered, how you solved them, and the outcome. For remediation roles, be ready to discuss contaminant types, remedial technologies, regulatory closure processes, and stakeholder management. For industrial hygiene roles, prepare to discuss exposure assessment methodology, sampling strategies, and regulatory standards you've applied. Practice explaining complex technical concepts clearly — consulting professionals must communicate with both technical and non-technical audiences. Also, research the specific Apex service line and geographic region you're interviewing with, and prepare thoughtful questions about their project pipeline and team structure.

Should I follow up after submitting my application to Apex Companies?

Greenhouse will typically send an automated confirmation when your application is received, so you'll know it went through. If a recruiter has reached out to you or you've had an initial conversation, following up after one to two weeks is appropriate and shows continued interest. After an interview, always send a thank-you email within 24 hours to each interviewer, referencing specific topics discussed and reaffirming your interest in the role. In environmental consulting, professionalism and attention to detail are closely watched — a thoughtful follow-up can reinforce those qualities. Avoid repeated follow-ups or contacting multiple people at the company simultaneously, as this can be perceived negatively.
