ALSTOM interview questions

I received a call after 2 weeks from submitting my application, they called to arrange an interview which it took place 2 weeks after the call. during the interview, they asked several typical questions. The interview last for 20 minutes, they were two managers, one from HR department and the other one from management control department. they informed that they were interviewing at least 10 others candidates. It took them more than a month to call me back and tell me that I didn't get the internship.

the whole process is fast and clear of each steps. I did not wait to long and get the offer within 30 days. But there HR is not very efficient .
