AEVI interview questions

Load Balancer implementation in Java. The interviewer knowingly extended the time and later said that time was running out. He said that information about the next stage will be provided at the end, but no information came from recruiter. Unprofessional approach.

There was intro call, tecnical interview and a hiring manager interview. All went well and discussed about joining date too. Then got a mail that they couldn't proceed further. Asked for the reason but i didn't get any reply
