Adecco Business Analyst Intern interview questions

After sending an email with my CV, I received a reply the very next day, which pleasantly surprised me. The interview was set for a week after their email. The Interview was pretty straight forward, though I believe it was long. 1.5 hours for intern maybe it's a bit too much. There was a good background check, and every point that I had in my CV. Person needs to be prepared to answer different questions about your projects and research skills. After the interview was over, I was told that I will be contacted in up to two weeks period. Two weeks passed, and I was not contacted. So after sending an email to them, I received a reply that they forgot to contact me, but it's kinda ok, because they cannot offer me the position.
