Data Patterns hardware engineer interview process typically includes an aptitude test on core electronics concepts, followed by technical interviews focusing on analog, digital circuits, problem solving, and basic hardware knowledge, along with an HR round evaluating communication skills, attitude, and overall suitability for the role.
Good technical interview in it and personal interview doesn't happen and hr round was personal and rude. The doesn't care about interviewes and just want bond to be signed before joining
