Actually, I was impressed how the OP handle his setback and how he took it as a learning experience.

Not to disagree with you here since this seems to be the sentiment here, but the questions (ie. boot process/signals) he was asked was broad and would have shown if the candidate have a solid grasp of Linux fundamentals.

Hypothetical situation, say he applied for sysad job in big Linux shop like Google. Describing the boot process would have given the interviewer an idea how well he would recover from a system crashed using a rescue disk. Understanding signals are important for making non-trivial Bash scripts. And describing a symmetric/asymmetric encryption is crucial if one of you job responsibilities is to administer certificates.

Not saying the questions are easy, they're not. But if you're applying for something like a Linux sysadmin job, then these questions are good indicator how strong your skills are in this area.
