Uber

Very nice, but difficult as only one coding question was asked. However, if you have sufficient preparation, then you can definitely crack it. There was also a system design round.

I had a math problem and was judged more on how I could use the correct formula, rather than understanding my problem-solving ability. I think the interviewer was looking for exact answers.

Screening round. Data structures & algorithms. Low-level design. High-level design. Hiring manager round. Hard DSA. After one round, all four will be scheduled. All rounds are virtual with a decent difference between them.
