Deem Software Developer interview questions

After applying online I had a first round interview with HR. It was a very casual conversation about the role and the company. The next round was a technical coding interview. I completed the challenge within 15 minutes and the interviewer then proceeded to grill me on design and architecture questions that he didn't even know the answer to. When I asked him if any of this was relevant to the job or similar to any duties I would have to perform he said no. I think they want someone who is way overqualified for the job listed but only want to pay entry level salary. The interviewer also mentioned that they can be expected to do a huge amount of overtime. I withdrew my application after the coding interview as I did not want to work for a company that does not believe in work life balance.
