Previous job (MicroCase): interviewed.
Current job (Respondus): recruited by VP from previous company.
MicroCase was acquired by Thomson Learning at the end of '99, I didn't feel like moving to Northern California so I turned down their offer to join them. After a few months of kicking back and doing a little part-time consulting, a VP from MicroCase asked me to join the startup company he was forming.
"Who you know" does help, but I got the Respondus offer because he knew I could do the job. He certainly wouldn't have spent his 401k money to pay me just because I'm a nice guy
