Dr. Reddy's R&D Manager interview questions

three interviews in total: first on the phone with recruiting agent, second online with Sales Manager, third - at the Dr Reddy's location - with the hiring manager and staff member. the whole process took more or less three weeks, Absolutely no answer: not a phone call, a message, an email. I took time to prepare, to do 3 interviews, to go there. I believe it says a lot about the company: run away.
