Tatvasoft interview questions

I applied for the BDE role and was contacted by HR. Despite agreeing to their US shift timings (3 PM – 12 AM) and their salary expectations, the coordination was poor. HR asked for my preferred time only to ignore it and set a fixed slot. After traveling 18km for a "1-hour deep dive," the interview lasted only 15 minutes and was conducted in a reception area with no cooling or fan in 38°C heat.

Interview process contains 3 rounds. Aptitude round, technical and last HR round. In Aptitude there are 75 question with negative marking. In technical they ask basic sql query(literally basic query), in HR round hr will ask for family background. And also aptitude question and ask for it's explanation that how you solve it and what is approach.
