Packsize Senior Software Engineer interview questions

HR and Engineering manger calls were really courteous and enjoyed really well. And third round was a pair programming session with TDD approach. I thought they were trying to see my approach not the result. It was the first interview since 10 years and I messed up little due to nervousness which I admit. I would have easily pull that api and return the result blindfolded on any other day. I have explained how should do it even it didn’t work and I was hoping they would have understood but anyway. I’m not frustrated about the rejection which was expected kind of but the way they ghosted me after the interview. Any company would have sent an email or make a courtesy call to say the result, even feedback on frequent follow up but not these guys. Even though Packsize is notorious on ghosting employees(I should have listened to previous interviews comment) I really wanted to get in PackSize for some reason, may be because of their product or it’s near by.
