Preparation

  • Every onsite round will evaluate 2 leadership principles. Recruiter told me not to repeat the scenarios across the LPs. So make sure to prepare well for this
  • I messed up Uber behavioural interview after cracking all technical rounds. So I prepared well this time
  • I didn't extensively practice for DSA rounds. I've made it a routine to solve the daily leetcode problem. I've been doing this since 6+ months, so I'm never out of touch
  • I read alex-xu system design book about an year ago. I felt my regular day to day work would be enough for HLD round. So I didn't prepare for this round
  • Concept and Coding playlist for LLD
