To succeed in the Addison Group interview process, you must prepare to showcase a balanced profile of deep technical expertise and professional consulting polish. We look for advisors who can seamlessly transition from performing complex thermodynamic calculations to presenting strategic recommendations to board-level executives.

Technical Domain Mastery – You must demonstrate an authoritative command of power generation systems, including legacy thermal assets and emerging clean technologies. Be ready to discuss thermodynamic principles, plant operations, and system performance metrics in detail.

Analytical & Financial Acumen – Technical recommendations are only as good as the business cases supporting them. You must show that you can build structured cost models, evaluate project economics, and align engineering decisions with the client's financial and regulatory objectives.

Client Advisory & Influence – As a consultant, your product is your expertise and your persuasion. Interviewers will evaluate your communication style, your ability to build trust quickly, and how you navigate difficult conversations with clients or contractors.

Project Ownership & Leadership – You will often work with minimal supervision, taking full responsibility for project deliverables. You need to demonstrate strong self-management, structured problem-solving, and a track record of delivering complex projects on time and within budget.

The interview process at Addison Group for our senior Consultant positions is designed to be structured, highly professional, and efficient. We value your time and aim to maintain clear, consistent communication throughout your candidacy. The entire process typically moves quickly, often consisting of four key stages that allow both sides to evaluate mutual alignment.

Initially, you will speak with a talent acquisition partner to align on your background, career goals, and the structural expectations of the role. Following this, you will progress through technical and behavioral discussions with senior consulting leaders and practice directors. These conversations are highly collaborative and conversational, designed to evaluate how you think, solve problems, and interact with clients.

The timeline shown above represents the typical progression for our senior-level advisory roles. While the process is rigorous, our interviewers strive to create a relaxed, productive environment where you can ask detailed questions about our projects, culture, and growth plans. Use each stage not just to showcase your skills, but to ensure our practice aligns with your professional aspirations.

Power Generation Technology & Thermodynamics

This evaluation area is the core of your technical assessment. Our clients rely on us for flawless technical execution, which means you must possess an advanced understanding of how utility-scale power plants operate under various configurations and environmental conditions.

Be ready to go over:

• Thermal Cycle Analysis – Deep understanding of Rankine, Brayton, and combined cycles, including efficiency optimization techniques.
• Emerging Technologies – Technical readiness levels, operational profiles, and integration challenges of Hydrogen, SMRs, and utility-scale battery storage.
• Asset Performance & Degradation – How ambient conditions, fuel quality, and cycling operations affect heat rates and long-term asset life.
• Advanced concepts (less common) – Carbon capture and storage (CCS) integration, fuel cell technology, and microgrid design.

Example questions or scenarios:

• "Walk us through the performance trade-offs of using dry cooling versus wet cooling systems in a combined-cycle plant located in an arid region."
• "How would you design a feasibility study for a client looking to transition an existing coal-fired asset to co-fire with 20% green hydrogen?"

Owner's Engineering & Contract Lifecycle

As an advisor, you will frequently serve as the Owner’s Engineer, protecting your client's interests throughout the project lifecycle. This requires a deep understanding of construction oversight, procurement strategies, and contract mechanics.

Be ready to go over:

• EPC and OEM Contracts – Key performance guarantees, liquidated damages, and liability limits standard in utility-scale agreements.
• RFP Development & Bid Evaluation – How to structure an objective, technical, and commercial evaluation matrix for multi-million dollar equipment purchases.
• Construction Quality & Commissioning – Best practices for monitoring schedule compliance, managing change orders, and witnessing performance testing.

Example questions or scenarios:

• "If an OEM fails to meet its guaranteed heat rate during commissioning performance testing, what steps do you take as the Owner's Engineer?"
• "Describe your process for auditing an EPC contractor's progress claims on a project that is slipping behind schedule."

Integrated Resource Planning (IRP) & Financial Modeling

Our consultants help utilities plan their portfolios 10 to 30 years into the future. This requires translating complex engineering data into long-term strategic and financial plans.

Be ready to go over:

• Levelized Cost of Energy (LCOE) – Building comprehensive financial models comparing different generation resources on an apples-to-apples basis.
• Scenario Modeling – Incorporating variables such as fuel price volatility, carbon taxes, and varying load profiles into planning models.
• Regulatory Compliance – Understanding how state utility commissions evaluate utility IRPs and what technical evidence is required to support a filing.

Example questions or scenarios:

• "How do you model the capacity value of solar plus storage assets when conducting an IRP resource adequacy assessment?"
• "What key financial assumptions would you challenge if a developer presented you with an overly optimistic LCOE for an offshore wind project?"

As a Consultant in our Energy Generation Services practice, your day-to-day work will be dynamic, intellectually challenging, and highly collaborative. You will act as a trusted advisor to our clients, helping them solve some of the most complex challenges in the modern energy landscape.

You will lead the execution of feasibility studies and resource assessments, serving as the technical lead on high-visibility projects nationwide. This involves performing rigorous thermodynamic modeling, evaluating technology configurations, and developing comprehensive capital and operating cost models. You will translate these technical findings into clear, persuasive strategic reports that help clients make multi-million dollar investment decisions.

During project execution, you will step into the critical role of Owner’s Engineer. You will oversee EPC contractors, review engineering designs, manage technical risks, and ensure that construction projects adhere to strict quality, safety, and regulatory standards. You will also support clients through the procurement process, developing detailed RFPs, evaluating bids, and providing technical leadership during contract negotiations for PPAs, EPC agreements, and equipment supply contracts.

Beyond project delivery, you will play an active role in growing our consulting practice. This includes staying at the forefront of emerging energy trends, deepening our team's subject matter expertise, and occasionally supporting business development efforts by drafting technical proposals and presenting our capabilities to prospective clients.
