(2 Questions)

  • Q1. Dont waste time on this one
  • Q2. Waste of time, evident from company reviews

Interview Preparation Tips

Interview preparation tips for other job seekers - 1. The interviewer, named Raghavendra, was quite rude. 2. He spent 10 minutes asking about the technology I was familiar with, followed by an hour of interview and later expressing dissatisfaction with the expected technology stack. 3. It seemed that he lacked prior interview experience and focused solely on a single concept. 4. He approached the interview by browsing a specific concept and expected the same keywords from the candidate. 5. This was an utterly disappointing interview experience; I have likely wasted the worst hour of my life. 6. The company lacks a clear culture, which was evident from the interviewer.
