Real quick – don’t bluff too much in an interview. If you can’t honestly say you’ve done something in the past – and back it up with examples – then tell the truth. People can see right through evasive answers and broad generalizations. Redirects are okay – “No, I haven’t picked up Ruby yet, but I am a quick study. When I took my job with Acme Falling Anvils, they had just converted over to Java. I was a C++ guy/girl up until then, but within three months I was leading classes fot the other engineers on Java.”
Don’t say yes to everything, unless you actually can do it all. It’s obvious, and a turn off.
