IMMI Engineer interview questions

Applied for job and was contacted approx 3 weeks later to schedule phonecall screening. Approx 2 weeks after phonecall had F2F interview with 4 different managers (individually), each for 30 min. Never heard anything back from them, hence the thumbs-down rating. Candidates that do a F2F deserve a response of some sort, even if it's a generic form-letter email stating you didn't get the job.
