IT services and consulting Interview Guide

Firms that sell delivery capacity and advisory work to clients, where the interview is partly technical assessment and partly a rehearsal of how you will sound in front of the client paying for you.

How the loop is evaluated & calibrated

Breadth beats depth here, because a consultant is staffed against whatever the account needs next quarter and the panel is measuring how quickly you become useful on an unfamiliar codebase. The rounds that decide the outcome are usually the case study and the client-facing conversation: estimation, scoping, what you do when the requirement is ambiguous, and how you say no to a client without losing the account. Presales and solutioning questions appear even for delivery roles at senior levels, since anyone leading a workstream eventually writes part of a proposal.

Scored on top of a correct answer

  • Whether you can explain a technical trade-off to a non-technical stakeholder in their language, and hold it under challenge
  • Estimation and scope discipline: what you would ask before committing to a date, and what you refuse to estimate without
  • Methodology fluency, because the delivery model is contractual here rather than a team preference

Where candidates lose points

  • Answering an ambiguous scenario with a technical solution before establishing who the stakeholder is and what they are optimising for
  • Treating process questions as bureaucracy, when the panel reads that as someone who will surprise a client with a slipped date
  • Depth-signalling in one framework while showing no evidence you can pick up the account's stack
