Privacy4Cars interview questions

The worst ever interview process Initially they told me 2 technical +HR round. After clearing 2 technical round they schedule 1 more technical round. Again they scheduled 4th technical round after clearing the 3rd one. All technical round has the same pattern of taking interview. After that they rejected me with no reason. Dont know if I would have cleared the 4th techical they might have scheduled 5th round as well.
