Nano Web Tech interview questions

So I had my 3 interviews, I went off to lunch, and when I came back my "host" came in with a new schedule addendum, with the 2 other people. I made random small talk with the host for awhile. Then I talked to the engineer for extra long because "Directors are always late". The Director came in and he was pressed for time, so we banged out his 3 questions quickly.

Their interview process in 3 rounds as 1st is Written Tech knowledge Test in a complete interview question answer sheet format, and then second oral round and 3rd round with Tech Team leader. .
