Received a call from some consulting company and I have taken their online written exam at HackerRank. 6 questions in 2 hours - medium difficulty 1 question on ETL scenario and 5 on Advanced SQL. After the exam I have received an email for F2F interview at their Hyderabad office. And then they went ghost, they ignored my emails and calls. They won't even take the call from consultants that first contacted me. In conclusion, the company has an unclear understanding of it's own HR requirements. To top it, they don't have the courtesy to respond. It's a mutual waste of time.
