Recently i gave Uber SDE 2 interviews. It took around 2 months to complete the whole process. I got rejected at the end but had good experience.

1. Online Assesment
   Got OA link which included 2 leetcode medium - hard questions. Able to solve both on them.

2. BPS Round(Business Phone Screen)
   One DSA question was there able to solve it with running code. It was of heap. I solved previously asked questions of uber and got a same one.

3. Coding Round (DSA)
   One DSA question was there able to solve it with running code. It was a new question never sovled it before. The question was related to maths and logic.

4. LLD Round
   They asked me to build splitvise application. The expectation was to have running code. I able to write the running code. As its a 1 hour round time is the real problem.

5. HLD Round
   They asked me to design a particular feature of e commerce site. I have to build the landing page where user will see the popular items which are trending.

6. HM Round
   He asked questions regarding my current company project. Asked me to design the HLD of the most complex work you did. Apart from that he asked some Behavioural questions like if any conflict happened kind of problems

Hope this helps!
