Applied through university recruiting, there was a first technical question to write on paper. After passing, I received a call for the first round of interviews.

The first round was with an employee from Redmond. The first few minutes were for introductions and small talk. Afterward, I was asked a question related to Binary Trees, which I managed to answer correctly. Following that, I was given another question related to the original problem, which I also handled well. The interview concluded with some small talk and feedback from the interviewer, a detail I appreciated.

A few weeks later, I received an email from the recruiter. He informed me that my interviewer had recommended me for the next round, and a final round of interviews was scheduled for the following month.

Honestly, I had studied very little, only reviewing some algorithms. The final round was entirely different, consisting of three back-to-back interviews, all in the same format as the previous round. I believe I performed well on the first two, but for the last one, I didn't connect well with the interviewer. He spoke very little and seemed more focused on his computer than on the interview. After a week, I received a rejection email.

As a tip: read 'Program Interviews Exposed' and 'Cracking the Interview Code.' Also, review algorithms and data structures. TALK ALOUD during the interview – this is very important!
