VMock interview questions

Just normal coding qns like implement a hashmap in round 1, in round 2 they asked to build a full application which took nearly 2-3 hrs and then round 3 they gave a 500 lines code and told to debug it which took like 20 min and then round 4 is with Founder which I didnt pass.

They asked how I would handle a client that’s about to churn and what steps I’d take to retain them.
