Worst interview is the one that actually got me where I am today.

Its been 15 years ago, but I remember very well. Since it was a startup back then they didn't really have any job titles yet or what so ever. I applied for the role of network engineer, heck I didn't care I needed a paycheck.

5 minutes into the interview the smalltalk left the room and they started asking me questions, mainly about me as a person. Eventually it was my turn. After my first question I facepalmed so hard.. Do you guys have any SLA or documentation around here? Heard of ITIL? How is your load balancing?

They stared at me as if I was some kind of alien that had just invaded their little safe planet.. it was hilarious.

An hour later they called me to come back in and sign a contract.. from there on I kind of multi tasked my way around the first year.. bit of network support & design, customer support, sending and packaging orders after 5PM.. god we had long but awesome days.. hence, we were just the 5 of us. Nowadays we've got 150 developers out of 1019 total staff currently.. We also improved interview questions and processes ;)
