Bit random if they call back. One was such an amazing interview that I didn't bother with anything else for a month. Honestly the guy was saying "when" I start, took me to his house, introduced me to his wife, everything. After a month I phoned up and he said he got someone else and forgot to phone me. Totally gutting.
And how many people to they actually interview?
When I used to work for a software house, when we were at our peak with about 150 programmers, our department (30 programmers) used to get around 100 CVs a month. Most we would chuck straight in the bin if they didn't have a CS degree or some kind or a funny name or CV (honest). We would still be left with about 20 CVs and would have a few days a month to interview everyone. Took ages. Eventually we used an IQ test thingy to weed out the more useless ones (no interview if lower than 90%), so was a lot easier. We also introduced a test after 3 months to get rid of the rubbish ones who got through that. Might miss a few real diamonds using those steps but we immediately stopped getting people who didn't know where the "O" key was and had a BSc CS degree on their CV... Much better.
Oh, and just remembered my best and worst interview ever. Was just after Uni and the only software house on the island (Anglesey). Right next to a chicken cooking place (stinks). Had an hour and half interview with the MD. Thought I was right in there. Was matey and everything. Then at the end he said obviously with employing 2 new YTS guys as programmers he couldn't afford a college grad. Aha. YTS... aha... Friend of mine left school the same time as me and was a manager there by that time. Aha...
Cheers
