I applied through other source. I interviewed at Quantcast
Interview
First I participated in the code challenge, which is something like a mixture of BFS and string match. After a few weeks I received email from the recruiter discussing the schedule of the interview. During the interview I was first asked to talk through one of my project. Then I got two technical questions. Question #1 is to find and remove all the duplicates in the array(unsorted), which I only came up with a brute force solution - sorting the array. Question #2 is to find the k smallest elements in N lines of data, where N is a fairly large number. I solved it with maintaining a min heap.
Interview questions [1]
Question 1
Remove duplicates. I could not solve it without sorting the array first.
Interview went with 7 interviews but got rejection because one person say no, all other says yes therefore I am confused that majority is saying and it is not about the technical part.
Take home assignment and follow up on the take home. Easy take home and easy follow up. Expect to explain your thought process and extend the take home assignment with another engineer.
Interview Screening - Talked to a hiring manager in a video call talked about the company, my experience, salary expectations, the next interview would have been a technical interview, and then a live coding interview.
