I was being interviewed for an MS program.
I was asked: so why haven't you applied for this program to the same school you got your UG from- your school offers the same program as well!
Me: yes I am aware of that. but I got my bachelors from xyz school, developed leadership skills etc there as well. and then got hired for a full time job at xyz. I want some diversity now- I can't be xyz' baby forever! "baby"?? I wished I had just stop at I want some diversity!

This reminds me one of my stupidest interviews.

It was way back in 1997, I was fresh out of school and internet was the "Magic" word then. I had seen computer only in our labs and had absolutely no idea what is internet and how does it work.

I was interviewed by one of the big internet company ... who had all those wonderful idea of switching on your heater, light before you reach home kind of stuffs!!

All the discussions went extremely well in a very open atmosphere. Then came the deadly question, what is internet?

I gave a big theory like TV, you got an antenna connected to your computer, you send microwave signal to a satellite and satellite relay that request to some BIG computer in NASA, which has all the information!!

The interviewer was amused but he was dead serious, nodding his head in agreement ... so I was encouraged more to elaborate my satellite theory.

I took a paper and draw the diagram, showing two way traffic!!

Interviewer was wonderful, he asked me to calculate the response time.

So I assumed half of the speed of light and came up with some time ... from my home in SEA to NASA and back!!

The interviewer was probably amazed too much and ask the next question ... these antenna and satellite has some latency, so you need to factor in all those delays ... so after discounting those delays what is the response time?

I honestly thought that my theory was bang-on!! So I paused few seconds and gave some thoughts and came up with my discounts with a reasonable time to open yahoo website!!

Now after playing with internet, I know how silly was my theory! and I respect my interviewer, he probably was enjoying my new invention!

In October, I interviewed at Tuck and then Duke in one week. For my Duke interview, travel had been a nightmare and I got very little sleep, so I was definitely feeling off my game. So, about halfway through the interview, I got asked "Why Duke?" and I pulled a kryzak: "Blah blah blah.. and that's why I want to go to Tu... Fuqua."

I was pretty embarrassed in the moment, but I think my interviewer either didn't notice my flub or appreciated how quickly I recovered because somehow I still got in.

For my 2nd job after college, I was so desperate to get an offer / show up everyone at my old company, I told my interviewer "Money doesn't matter ... "

Edit: I got the job and took it. Felt like a stud for a few weeks at my old company, than my suffering began all over again.
