The Principal Technical Recruiter and HR team made sure everything was smooth and that the process was crystal clear. I was referred by an employee at comScore. The interview process started with the Principal Technical Recruiter asking a few questions relating to my background and skills. Later I was briefed on what the team excepts from a potential candidate. Then after a week I got a thumbs up and was asked to schedule for a phone screen interview. The interviewer was a Senior Software Engineer and the interview was on coding (Java). The question asked was to write a program to find if two given strings are Anagrams. There are multiple solutions and I came with the one that had best time complexity, then interviewer asked if I can do better on space complexity. After that a discussion followed on which of the solutions would be better under what circumstances. NOTE: This was coding intensive round and the code typed is expected to run with minimum errors. There was an option to choose from an IDE platform to code but I choose the non-IDE one. The interview lasted for 45-60 mins. The next day I got a reply from the Principal Technical Recruiter and was told that I did well and that the team wanted to schedule a face to face interview at their HQ's in Reston. The on-site interview had 5 technical rounds with 4 of them being on Algorithms, data structures and Big-Data and the other round was on Machine Learning. Questions were asked on linked-Lists, Trees, Stacks, Lists, Sets, Maps, MapReduce, data types (primitive, Wrapper and Box), Pig and other brain teasers. The team that interviewed me was great and very friendly but technical intense. Once the interview was done I was briefed of the next steps and told that a decision would be given in the next 3 days and they did send me out an offer letter on the third-day. Benefits: They offered more than what I asked for with all the benefits, also the company sponsors H1B which is great. They try their best to give any other allowances that a candidate needs. TIP: Be prepared. They won't ask anything that is not on the job description or that isn't on your resume.
