Numeca International CFD Development Engineer interview questions

I applied for the combustion modeling engineer position. Received an e-mail shortly afterward to arrange a skype meeting with the head of the combustion modeling group and a few other developers from other groups. The interview was fine, I simply talked a little bit about my masters and PhD projects. They occasionally stopped me to ask some questions. Afterwards, they asked a few follow-up questions, and we had a short discussion about some of the work being done at the company. There were a couple of other roles they were looking to fill as well, which they figured I might be a better fit for as I had more experience in them. Shortly after, I received a request for another interview, with some of the same interviewers, and a few different ones. The tone of the interview was quite different. They regularly interrupted my presentation to ask questions, many of which would be answered had they just waited for a few slides. Some of them were simply out of the scope of what was supposed to only be a 20-minute presentation. The tone was often quite standoffish, and what was supposed to be a 20-minute presentation dragged for about 45 minutes, so there was little time for follow-up. I kind of lost interest in the company after this interview, they struck me as quite arrogant, and working in that kind of environment would not be enjoyable at all. Fortunately, I received an offer from another CFD company which left me with a much better impression.
