Apart from regular technical questions and tricky questions that are aimed at catching you off guard, you can expect an unknown and weird technical question to be thrown at you when you take up a machine test of any sort. This weird question will be from this company's client project that they are currently working on which they are not able to solve using their own brains. So you, the hapless candidate, who is looking for an opportunity will be given the task of solving it for them. Without pay or compensation or any form of benefit. Then the team lead will have the audacity to comment that he is not impressed with your work as you did not meet his expectations. Their interview process is plain BS. Literally.
