I applied through university. The process took 5 days. I interviewed at UTC Aerospace Systems (White Field) in Feb 2019
Interview
Good but had to wait for whole whole day that is from morning to evening just for 20 mins interview but the atmosphere was good they provided lunch also. Interview was also good they were looking for some specialist which they should have mentioned earlier then it would be great.
It was a single interview with technical and HR rolled into one. There were three interviewers - while one took the technical interview, the other two went through my resume. The interview process was overall quite good, however I found the interviewers to be somewhat unprofessional in that they were making unpleasant expressions every time I gave an answer they didn't like / was wrong.
