Funny. Sounds like me. I went to a decent but "wrong" school (UVA), lured by promises of a free ride. I missed my tech bingo interviews (and I've had a lot of them), for reasons worthy of a blog post. My first, for instance, with MS, went wrong because Alaska Airlines got my flight in around 1 or 2 AM - for an 8 AM interview the next day. I know I was not at my best.
I am also totally done with Google - it's just not worth 4 months of runaround and countless phone interviews just to come in and fail because one of the interviewers hates the whole process. And last time they contacted me, they told me to learn either Java or Python and call them back when I did. No thanks. Nothing against Python, but I am not putting that much effort into the chance at another interview. I would totally work for a company that did Python, and learn as I go - I've done that plenty before. (Edit: Oh, and the number of interviews google puts you through just should not be allowed)
I spent a year working on my own startup, which is what got me into rails, but it ran out of runway and I was then tied to the area by romance, and got a mediocre job at a huge company. I am no longer encumbered, but my resume lacks any recognizable names (of schools or companies). I've had a lot of other personal projects that never went anywhere and which earn me no points, but at least keep me in the game. (I should have put them all on GitHub, I suppose, but was too embarassed about their unfinished nature to do so).
I also don't get what the obsession is with CS 201 questions. But I keep my data structures textbook around just so I can relearn how to implement A* or remind myself what the big-O of a B-tree delete is before interviews. Of course, at Google I'd need to be implementing these data structures daily(?). I don't have a big problem with them, it's just an odd thing to be obsessed with.
