I was interviewed by a manager and an expert. Everything was smooth. They went through all details from my background and even my PhD thesis which was from 10 years ago. It took about two hours. In the end, they said I will hear from them in two weeks. I never heard anything back. I followed up with HR and the people who interviewed me after 3 and 6 weeks. No answer!!! Then I gave up because I had a better offer from another company.
