Summary
I interviewed for an L4 role at Uber in Bangalore and received an offer. The interview process included a HackerRank round, a phone screen, two DSA rounds, LLD, HLD, and a Hiring Manager round, with initial negative feedback in LLD and HM rounds that was later overturned.
How it went
Experience: ~3 yrs
HackerRank Round: 4 questions had to be solved in 90 mins. Question were medium to hard difficulty.
On clearing hackerrank round, 1 phone screen round was scheduled
Phone screen

After clearing phone screen 4 rounds were scheduled
DSA 1
Started off with this sliding window problem - https://leetcode.com/problems/maximum-points-you-can-obtain-from-cards/description/
And then asked - https://leetcode.com/problems/cheapest-flights-within-k-stops/description/
LLD
Design a parking lot system with the following specifications:
- The parking lot consists of multiple levels, and each level contains multiple rows of parking spots.
- There are two types of vehicles: motorcycles and cars.
- A motorcycle can park in any available parking spot, regardless of the spot type.
- A car can only park in a designated car spot.
Also implement park, unpark and search functions.
HLD
Send push notifications to users subscribed to a stock when its price jumps or drops more than 5% compared to its closing price.
HM
Don't remember all the questions but here are a few -
- Tell me about a time when you received critical feedback from your manager and how did you handled it
- About a time when you had to work with someone outside from your team
- Had some conflict with co-workers and how did you solved it
- Too many back to back questions on everything I say.

Initially, HR informed me that I received negative feedback in the LLD and HM rounds, which came as a surprise to me because I had provided working code during the LLD round. I mentioned this to him, and he told he would update me after the debrief. In the end, I received a hire call overall. The only negative point raised during the HM round was my lack of mentorship experience.
I feel that HRs sometimes try to downplay the offer if you don't have competing offers.
