Overall, I had a very positive experience interviewing with Analysys Mason, interviewers were professional and created a positive, engaging environment.
The process included a recorded video interview (2 or 3 questions), followed by a first-round interview with motivational questions (why Analysys Mason, why consulting, why TMT) and a business case. The next stage involved a pre-prepared presentation on a TMT topic, along with another business case and a brainteaser.
