After a thorough written test, I did a one hour technical Skype interview. The phone interview was mostly on the work I did earlier. I was invited for an on-site interview about 6 weeks later due holidays. My experience until this point was very pleasant and straightforward. The on-site interview, however, was an absolute mess. After booking a flight for half way around the world, I was schedule to interview three separate people (Senior Image Quality Manager, Senior Engineering Director, and HR). As soon as I walked into the building I got a distinct impression that they completely forgot that I was planned for the on-site interview.

The team leader just came back from the his holidays and asked me to wait for awhile. He came back after about 30 mins and we mostly went over the same topics that we did on the phone interview. After only three hours of face time, he said the interview was concluded. I was planned to do an interview until 5pm and asked why there wasn't an interview with HR. He went around and found the HR person(who he initially thought was away due to the holidays and muttered something about HR interview being pointless) and we quickly did a standard personality questionnaire. Of course, I never even met the director and I never really saw the building other than the shop and few desks right beside the conference room.

At the end of the day, I don't even know why they bother to spend all that money to fly me over if the interview was going to be finished in 3 hours. If the only person I was going to see was that team leader, why bother to schedule an on-site interview?

How would you measure the noise of a sensor?
