Uber | Software Engineer 2 | Interview Experience

Background: YOE: 2.5 years, Currently working at a PBC

Round 1 : Code Signal Assesment (70 min) This consisted of 4 DSA problems. I don't remember the exact questions, but the first two were easy, the third was of medium difficulty, and the fourth was medium to hard.

Round 2 : Zoom Interview (1 hr) This is an elimination round. I was asked only one question. https://leetcode.com/problems/reconstruct-itinerary/description/

Rounds 3 and 4 are conducted in person at the Uber office on the same day. Candidates who clear both rounds proceed to Rounds 5 and 6, which are also held face-to-face on another day.

Round 3 : Data Structures (1 hr)

I hadn't seen this question before the interview. I managed to come up with a recursive solution during the interview, but the interviewer asked for an optimized approach. I later discovered that it's a well-known problem, couldn't find similar question on LeetCode.

Round 4 : LLD (1 hr)

It was more like a machine coding round, where I was given a set of use cases and had to design classes and implement the solution accordingly. The round was conducted on CodeSignal.

Got rejection mail the next day
