First step is a phone screen with a recruiter, consisting of mostly questions about your resume and experiences. If you pass this, you get invited to an onsite interview.
There will be a meet and greet social event either before or after your interview. This is a chance to interact with current Captech employees. The food and drinks provided were pretty good. Also, Captech books a hotel for you and flys you in if necessary. Otherwise, they will reimburse you for driving.
This is probably the most important part, the actual interview, which consists of 3 interviews (2 behavioral, 1 technical).
behavioral interview: you will get asked questions about your previous experiences. you will also be asked why consulting and how you would explain a specific technical concept to a non technical person. lastly, expect questions about teamwork and classic "tell me a scenario when you ..."
technical interview: this is a typical white boarding coding interview. if you aren't familiar with these, you basically solve coding problems on a whiteboard while talking through your solution. I would say Captech's technical interview has less of an emphasis on the difficulty of the questions, and more about communicating with your interviewer while solving the problem. I would recommend talking through multiple solutions for a certain problem, and the pros/cons of each.
