Although the interview itself was nice and people were easy going and pleasant to talk to the rejective feedback on the interview (1 hr on-call + 1hr of code exercise + 3 hrs on-site) was provided in a very concise and short form without any details elaborated after one week of waiting on the last calendar day of month and two broken promises to come up with it (initially was promised to be given in two days). Very surprised to find such a disrespectful attitude after initially good impression at the first glance. Regret the time being wasted thereby and won't be endeavoring the second attempt ever.
