communication for the interviews is okay but they will not provide feedback you have to call them several times after that also sometimes they will not responding or ignore your calls

I got a call from the HR of the company, she took all my details asked for my current salary and expected. I said I can negotiate for the right opportunity, so leave that open, but she insisted on a number. I gave that number to her and went for an interview next day as requested. The interview time was exactly when my shift starts in my current organisation, so I had to take a leave. When I went to their office in Andheri east, I had to sit outside in the corridor waiting lounge for more than 30 mins, they made me fill a pre application form. After 30-40 mins of wait I finally saw the hiring manager coming out. He asked for me and said sorry you are outside or current hiring budget range and I cannot interview you. He did apologize for the inconvenience but this was highly unprofessional. I serious lack of communication between the HR and Operations. I will never in my wildest dream can recommend this unprofessional company to anyone.
