Cognex Software Developer interview questions

Another one of those companies that you interview for four hours, then get homework and then they don't have decency to get back to you because they must be so busy. The economy is turning around, people are going to start job jumping again. You best figure out how to treat prospective employees better. I think the earlier reviews were correct, this company has gone downhill.

I had a phone interview with the head of the company after having spoken to an HR person. The interviewer asked me a question which was simple enough. He asked me whats the purpose of a line like this in C: "a++=b++" where "a" and "b" are both pointers. I got stomped and didnt give the right answer. I think the question was fair but I do get nervous in interviews and this was certainly something I would have known. After I gave the wrong answer he gave me a huge lecture on how im a novice programmer and I dont really know much about coding in C. I felt bad enough for missing a simple question but then had to endure the lecturing by this fella. Sure enough, dont give me the job because I didnt get the question, but please dont tell me what I am and what I am not.
