It's worthwhile to interview the people you've worked with as they change over time, usually for the better with Junior Engineers becoming Senior or Principal Engineers, DBAs becoming engineers etc. But sometimes a long stint in management or getting stuck in KTLO hell for a few years can dull technical skills.

That's a fair point. Perhaps this is what people are talking about the conversations over lunch. I find it hard to believe that someone who wants to work as an IC and knows you would try to do that knowing their skills had dulled. The shame of failing someone who trusted you to deliver would be too much!

> DBAs becoming engineers Excuse me. Most of the top DBAs in Silicon Valley are former C programmers who probably are better programmers than you. I wish programmers would get over themselves. I've met CTOs who didn't know EXPLAIN. So who's the real engineer?

  What is EXPLAIN?

    SQL command to show how a database engine will execute a given query. I wouldn't necessarily expect a CTO to know about it, to be honest, unless their background was somewhat database-y.
