Was highly unprofessional. The entire interview (3 stages in all) was scheduled using a means of SMS and Whatsapp. When I asked for the interview schedule to be emailed, HR claimed that they had send it out week ago in advance despite no follow-ups from HR as to whether the email on the interview was received and if I was alright with the schedule!
The second round was conducted in a highly noisy environment. Interviewer did not make the effort to find a quiet room for the interview
