OA1 - Q1 10/10, Q2 4/10
OA2 - Think I did well

Onsite (3 Rounds x 45 Mins)

• Round 1:

  • LP Question
  • OOD question similar to LRU Cache, LC Medium
  • Came up with optimal solution with time left to dry run and write test cases, interviewer seemed happy

• Round 2 (Bar Raiser):

  • LP Question, probably could have done better
  • https://leetcode.com/problems/integer-to-english-words/
  • I did this question once before
  • Not as structured an approach to solving this, asked a couple of clarifying questions and mentioned that I could use recursion to build up a solution
  • Did not ask me time complexity or to dry run the code (Possibly because I was doing dry runs of the code while writing it to guide myself to the correct solution)
  • 3 Follow ups of which I was able to answer two before we ran out of time
  • This is probably the round I'm most unsure of

• Round 3:

  • LP Question -> Different question but I ended up using a similar story to the previous interview
  • Asked about a previous full stack project
  • Custom question OOD around LC Easy/Medium
  • Had a lot of questions about it, but was able to clarify and build to a solution
  • Was able to correctly answer follow ups and the time complexity for those follow ups

Overall I feel confident that I did well throughout, I was able to solve all 3 questions and arrive at optimal solutions, the 2nd one was kind of iffy as I didn't necessarily have an approach set in stone, but by dry running through the code, I was able to arrive at a correct solution, I felt my LP story may have been weaker here as well but I'm not sure. I am confident that I did very well in the other two rounds.

I hope this helps some of you. I did about 200 LC questions leading up to the interview.
