G-Research interview questions

Contacted by a recruiter, arranged first round phone interview Passed the interview, and then the recruiter informed me that there were no roles that matched my profile. So why did you waste my time interviewing me?

1. Call with the recruiter. 2. Call a software engineering manager. This is a 1-hour call, with the shoot and answer questions. If you do not know the answer, just say "Pass" and it is completely fine. The second part is a Programming Question. Typical DS and Algo questions in easy-medium scale. 3. Final round with 3 parts, with first being pair programming, ds and algo, and systems design. Standard questions.
