Got the phone call when I was outside in noisy environment. So we decided to have the call after 1 hour, and I was given a time slot that was 2 hours long (14-16:00). BUT no call came. I sent an email at 15:59. Finally got the reply and apology at 16:47 and agreed to have the call on the other day without giving me a exact time, just saying "morning". Gladly, they gave me a time slot after 2 days by email. Finally did the phone interview after 2 hours when being informed of the time slot. Phone call last 11min with 3 questions.
