Interview Preparation Tips

Interview preparation tips for other job seekers - They took 5 rounds of interview. 3 of them were technical and had easy to moderate level of questions. Rest 2 were more of HR rounds.
After taking 5 rounds, they have the audacity of not even calling back, picking up the calls or providing us with any information. If you are not interested in taking the candidate then why waste their time?

Funniest part is that they are fully aware of what a rubbish organization it is. In the later rounds they talked about cost cutting, negative news around the company, and employee complaints for work life balance. However, they are great at gaslighting as well because they make these sound like employee problems not employer problems.
