College: B.Tech(Computer Engineering) from 3 college in India
Position: SDE-1 at Amazon
Location: London

Recruiter emailed me if i am interested in Software Engineer, Product position at facebook london. Obviously I was interested.
Had phone screen round first:

• Two questions asked, find out if string can be made palindrome by removing at most 1 character and find subarray with sum = k. Nailed both the questions.
• Onsite got scheduled for 3 weeks later:
  • 1st problem solving round: Clone graph and running average of an array of k elements.
  • 2nd problem solving round: LCA of two nodes and create max number by swapping at most 1 number. Like 123 is given then return 321 (swapped 3 and 1).
  • Product design round: Design an online code judge.
  • Behavioral round: Standrad behaviroal questions about my team, experience, conflicts, what are the things that excite me, sitation based questions etc.

Got rejection after 4 days. Facebook by far has the best recruiters, best overall experience from prep call to interviewers to recruiters replying withing few hours. Will try again next year.
