Hi Everyone, I applied at Walmart for senior/staff role and had a phone call with the recruiter where he asked me basic questions like, tell me about yourself, location etc. It went well. The recruiter said I am a good match for the job. Then I had first technical interview through Karat. This is where it went the other way. Here's how my interview went: First 10 minutes: We did introductions and I told him about my experience and projects. Next 20 minutes: I had to make an API structure. I made it successfully. He asked me how would I set Cache for faster API calls (I didn't know this, so I politely told him No) Next 30 minutes: I was given a problem. I solved it successfully under 30 minutes. He asked me about time and space complexity. I told him correct answer. BUT I got rejected and didn't get any more feedback I think it was because I took more time in solving these questions. Maybe the interviewer wanted to present some more questions/problems. (But shouldn't they give all questions to you at the start of the interview if this is the problem?) Anyways, would do you guys think about this?
You dodged a bullet Walmart is a shit company to work for
I don’t have any job atm so any job will suffice
A lot of interviews are structured to make you feel positive about the experience even if you bombed it. You're probably right that the interviewer had more questions, but the time had been used up

You never implemented a cache before?
No
Like not knowing some algorithms from school or not solving a difficult coding problem is fine but for a senior+ saying “I don’t know” when asked about scaling an api with a cache is totally unacceptable.
