AppsFlyer interview questions

First meeting: meet with the direct manager, then with a trusted team member. Second meeting: meet with 3 team members (including the manager) for a group panel where I had to sell them their own product/services. Third meeting: meet an HR representative to discuss the company and to find out more about me and professional goals.

Standard interview questions (why you, why AppsFlyer) plus few specific mobile related questions. Many rounds including CEO, everything took more than a month. They called my references. Positive feedback after all rounds, also after the last one. I received a contract template and we were discussing the starting date. Then all of a sudden a few days later they called me that they actually decided not to hire me and literally refused to give me any explanation!! Extremely unprofessional situation handling from the company and a very disappointing experience for me.
