Overall 4 rounds: 1. Intro round LLD discussion + Product Thinking Design Food Delivery. I asked that Let me create a class diagram as well but he was not interested. Then we discussed API inputs and possible outputs. Two things here that they should improve is that they should tell the candidate it is either a product question or a tech question. 2. CTO Round: Firstly he came late I think he was sleeping and we brainstormed about a few situations in the previous product. Why socket programming, 3. Android Round: It was taken by SDE Android. Very basic questions related to android. I did answer like 99% of them but came to know from the agency that this was the round where they rejected me and I was like WTF. 4. Hiring Manager: Again 2 DS algo question. Coded and solved in 15 minutes and he was impressed. 1 simple Database Question and then Behavior Questions. I used STAR framework to answer all of them.
