TSG Consultant interview questions & guide 2026

The following questions reflect the core competencies TSG looks for in a Consultant. While these are representative, remember that your specific interview will be tailored to the product stack (e.g., Sage Intacct or Business Central) relevant to the team you are joining.

Technical and Product Expertise

These questions assess your depth of knowledge regarding the specific software platforms TSG supports and your ability to diagnose technical issues.

• How do you approach troubleshooting a complex error in Dynamics NAV that isn't documented in the knowledge base?
• Can you explain your process for performing a data migration or system upgrade in Sage Intacct?

Preparation for a Consultant role at TSG should be focused on articulating your technical depth while proving your ability to handle client-facing responsibilities. You must be able to connect your technical skills to the business outcomes that TSG delivers to its clients.

Technical Proficiency – You must demonstrate deep knowledge of your core ERP or support stack. Be prepared to discuss specific modules, configuration nuances, and common troubleshooting methodologies used in your previous projects.

Client Communication – TSG interviewers look for a professional, consultative tone. You should be comfortable explaining technical trade-offs in a way that respects the client's business goals and operational constraints.

Problem-Solving Methodology – When presented with a case or technical scenario, focus on your process. Explain how you gather requirements, isolate the issue, test potential solutions, and verify the outcome before finalizing the fix.

The interview process at TSG is designed to evaluate both your technical competency and your cultural fit within their service-oriented environment. You can expect a rigorous assessment that moves from an initial screening to more in-depth technical discussions and, potentially, a practical assessment or scenario-based interview. The pace is typically steady, reflecting the professional and client-focused nature of the firm.

This timeline provides a high-level view of the progression from initial contact to final decision-making. Candidates should use this as a framework to manage their preparation, ensuring they have refreshed their technical knowledge before the deeper technical rounds and prepared their behavioral stories for the final stages.

Technical Troubleshooting

This is the cornerstone of the Consultant role. Interviewers want to see how you think when a system fails. A strong performance involves a methodical, logical approach to debugging, showing that you can navigate logs, configurations, and documentation effectively.

Be ready to go over:

• Root cause analysis methodologies.
• Version-specific features and common bugs in your area of expertise.

As a Consultant, your daily work involves a mix of project-based implementation and reactive support. You will be expected to manage your own queue of tasks, ensuring that both long-term project milestones and immediate support tickets are addressed with precision.

Collaboration is central to your success. You will frequently work alongside project managers, other technical consultants, and the client’s internal IT or finance teams. Whether you are performing a 3rd-line investigation for a service desk ticket or configuring a new Sage Intacct module, you are expected to maintain clear documentation and provide proactive updates to all relevant stakeholders.

To be competitive for a Consultant role at TSG, you should possess a solid foundation in the relevant software ecosystem.

• Must-have skills: Deep experience with the specific ERP or software stack (e.g., Sage Intacct, Dynamics NAV, or Business Central), strong analytical skills, and proven experience in a client-facing or support-heavy environment.
• Nice-to-have skills: Experience with cloud migrations, SQL database management, or certifications relevant to the specific product suite.

Candidates should have a history of working in environments where accuracy, reliability, and clear communication were paramount.

• Understand the client's perspective: Always frame your technical solutions in terms of how they help the client achieve their business objectives.
• Prepare for the "Why": Be ready to explain not just what you did, but why you chose that specific approach over other potential solutions.
