Their HR/recruiter send me a message and then we had a quick call and we discussed as a general HR interview. A couple of days later she arranged a technical interview and I attended the interview. It was an average interview and went pretty well. The day after, I sent a thank you letter to the HR. She replied me again and told me their technical team have had positive feedback regarding my interview and she will let me know by end of the week. I send her an email the next week and the week after, as she didn't get back to me. She didn't even reply my emails. So unprofessional and disrespectful!
