Application

I applied through a staffing agency. The process took 2 weeks. I interviewed at Quantcast (San Francisco, CA) in March 2015.

Interview

First had a phone conversation with recruiter. The recruiter was very nice and pleasant to talk with. Worked on a take home coding exercise and it took about 3 hours to complete. The phone screening took about an hour. A few days later I got the onsite interview invitation. The onsite interview took a few hours, met a few engineers and mostly worked on coding and algorithm.

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

I was emailed a coding challenge that I was to take 4 hours to complete. I found the challenge difficult to complete within 4 hours and I did not do well enough to move to on site interviews.

Interview

First they set a Phone Interview (1 round) - 45 minutes to 1 hour. It involves coding on a shared doc with one developer there. They call you for an On-site Interview (if phone goes through well) and you need to fly to SF. They are willing to cover the expenses.

I applied through other source. The process took 2+ months. I interviewed at Quantcast (San Francisco, CA) in June 2015.

Interview

Linkedin InMail -> Phone interview -> Take home task (fun question) -> Onsite

Interview questions with Quantcast are not easy but lots of fun, interview includes Data Structure/Algorithm and System design questions. The good part is, those questions are sort of open-ended questions, so it is not like those boring ones which you can find on some websites.

I enjoyed a lot of this process, people I spoke/met with are very smart, passionate.

HR is professional, nice, helpful!

Interview

Phone Screening(HR), initial technical and personality phone interview with the team manager. coding and researching exercise. not super hard but lots of fun to do, I would say it's pretty technically challenging and you will have a lot of fun working on it. I didn't use map reduce approach because the time wasn't really sufficient for someone like me, who is not really a mapreduce expert.

I applied through a recruiter. I interviewed at Quantcast in February 2016.

Interview

Introductory call was nice but the technical phone screen was nonsense. As soon as the interviewer said "Hello", it became clear to me that he wasn't really interested in doing the interview and was simply going through the motions. I don't really know what he had against me - maybe he felt threatened by my credentials? My accent?Who knows.

Anyways, after introductions he started chewing food loudly into the phone as I was answering the questions, which was rude and unprofessional. I lost my enthusiasm because I absolutely did not want to work with such a person. I wanted to end the call there but decided to complete the interview just for practice.

His questions were vague and he was basically looking for excuses to fail me. The guy obviously has issues but he is not going to tell his co-workers what his issues are. Instead, he will continue to quietly sabotage candidates he won't like, wasting everyones time. I'm glad that I am not going to work for a company that has people like him in senior positions. It means that theres all kinds of politics going on in there. Those positive employee reviews here now look fake to me.

To sum up, don't waste ur time with them. You can use them for practice but I wouldn't waste a full day on an in-person interview.

I applied through college or university. The process took 4 weeks. I interviewed at Quantcast (San Francisco, CA) in September 2015.

Interview

I partitipated in the coding challenge, and then invited to the onsite interview. BUT it has been more than six months and they still haven't reimbursed me for the travel expense. This is really annoying. And I have seen many such complaints (they do NOT reimburse the candidates) from other websites.
