First round phone interview (1 interviewer): Solving a medium-level algorithm problem.

Second round video interview (2 interviewers): Details about past projects; a medium-level algorithm problem.

All three interviewers were very nice and helpful. Unfortunately, I was rejected. The feedback from the second round was "doubt about the applicant's teamwork ability." I believe I overemphasized my individual contributions during the background explanation, which I can avoid next time. Nevertheless, it was a great interview experience where I learned a lot.

R1:

A medium-level algorithm problem (writing the code in an editor). After figuring out the solution, the interviewer asked something about the intrinsic nature of the data structures I was using (like hashmaps, vectors).

R2:

Detailed explanation of my past projects (writing the code in an editor). Some questions about teamwork. One medium-level algorithm problem.
