Couldn't agree more: I look at the max allowed number of characters on website X and I ask 1Password to generate a password of that length with whatever complexity the website allows (so preferably numbers and symbols if allowed).
Really depends the type of work you like to do. Consulting companies like you to know a bit about a lot of things.
Product companies on the other end tend to hire for very specific roles and will thus be looking for specialized folks (e.g. Apple hiring CDMA experts).
