Thinkify interview questions

This company hires people mostly for Swiggy or Flipkart as a contractor. The interview is mostly taken by the client itself apart from the first round. Client rounds can vary from team to team. The first team in flipkart that I interview for had 3 interviews for SDE-1 and 4 for SDE-2. The interview consisted of Machine Coding, DSA, System Design(SDE-2) and HM rounds. I couldn't crack the DSA round. Later I have interview for two more teams where there was only DSA and HM rounds. I cleared DSA for both but failed in the HM rounds.
