I had a great experience with the whole process. The interviews felt well run, and the technical evaluation was both focused and in-depth without dragging on with too many rounds. I remember the questions being technically hard and related, and the interviewers came across as skilled and prepared.

The director round also took place as part of the loop, and I appreciated that the questions had depth rather than just surface-level checking.

For experienced roles, I felt the expectations were very specific. The questions leaned heavily into networking knowledge with an emphasis on precise understanding—especially around material from the L4 to L7 level range.

The process itself was pretty simple in terms of structure, but the content felt intense. I had to be ready for questions about my past experience as well as live scenarios, and since it was a senior position, the interview felt like it could quickly overflow into more in-depth scenario questions.
