Tell us what you think is missing. You don't "feel nearly prepared". Have you prepared? These interviews (for better or worse) tend to be algorithm based. How are you on those?
To meet your points: A) I haven't really put myself out there in a while(over a year), I've been 'prepping' B) My algorithm's are poor. While I understand the concept of Big O notation, I can't readily look at something and say "oh that's a _______ sort"
* (not that algorithm knowledge isn't practical, but for a lot of smaller, "web-interface-around-a-database" startups, they're not nearly as important as being comfortable around a full web stack)
The things I build now are essentially web interfaces sitting on databases. The problem is they aren't exactly.. or at all.. legal.
Great learning projects (putting my home video library into a web interface, with episode data from a TV series API) but not something I feel I can show.
You should "prep" your algorithms knowledge - it plays a big role in a lot of interviews.
