Yelp Senior Software Engineer interview questions

THis was the first round of yelp process. it was an online coding round using hackerrank. The difficulty was medium and there was only 1 question and 45 mins, which was enough time to solve the challenge.

Went through seven rounds of interviews only to be told at the end that the position I was interviewing for was no longer available. I chatted to the recruiter and they said that I had met all the criteria and actually did really well on the final round interviews. Basically I should have had an offer but they messed up. This mess up from Yelp cost me a lot of my time and my energy in preparing. Interviewers were really good, polite and answered all questions and found them easy to work with. First round - Offline coding test on HackerRank Second round - chat with Tech Recruiter Third round - data structure and Algorithm based question on Yelp Beans (internal product). Final rounds - two technical and two non technical rounds. Problem solving, software engineering, behavioural round and team player round.
