Telephonic interview and then a hiring event in Hyd.

It was one of the easiest interviews I had, completely unexpected from a company like Facebook. There was a limited set of questions, with one question per round. In total, there were two coding questions, one design question, and lastly, a cultural fit round.

It's completely unfair to have such a small number of questions, especially when they are relatively easy. This doesn't leave much scope for creativity and thinking, and a small mistake can prove to be too costly. In comparison, Google, Amazon, and Microsoft each have four to five rounds with two to three questions in each round, thus giving enough scope to express yourself.

Questions asked in the event:

• Implement hashmap
• Count distinct numbers in a large file
• Design a pub-sub system
• Design a Twitter feed system
