The first round was with the HR with them explaining about the company culture, job description and salary expectations. Post which they asked about my availability for the following week for interview with the manager, being an international student I explained them about the Visa situation and they said they would get back to me. Its been 4 business days since that and they haven't responded to any of the calls and mail to update, being an international student we are already on the clock so an update would have been immensely appreciated. Don't know how one goes from scheduling an interview with the manager to no response.
