I gave one efficient solution for everything. They wanted more than one. When i asked for a feedback after a week. I got the answer i was good but still interviewing others and didn't give me a timeline for a decision. Idk if it was a polite no or its a fact. But its been a month now. And they haven't gotten back; which i think is rude. So i guess i got passed along. Interview organization was not very efficient. There wasn't a lunch break during the interview process, didn't offer to pay for my parking. Hiring manager didn't seem very interested; idk the reason for that. Having said all this the technology stack and the line of work seemed very interesting.
