Ask HN: How do I interview better?

Over the past 4 months, I've spent dozens of hours talking to internal recruiters, developers, and product managers while interviewing to various tech companies. Apart from an offer that I regret turning down from half a year ago, I haven't made any progress or gotten offers at the companies I want to work at.

##Details First, some details about me.

- Programming seriously since high school - Graduated in 2012 from middle tier CS school. - Working for almost 2 years. - come across as young at 23. - Lots of Android/AOSP/Java experience, moving towards: automation/web scraping/"data science"/"machine learning"/Python.

2. Organizer of 2 separate programming meetups in NYC. 1. Meetup #1 is educational + adults - Consistent weekly meetups. - Going on for 11 months, since January 2013. - At least 500 attendees, possibly much more. - I helped start it up as subsection of bigger meetup. 2. Meetup #2 is educational + kids - Once a month 3-hour workshops. - Somewhere on the order of 500 attendees for 2013. - We create our own curriculums.

3. No outside work projects. - I talk about the projects at my current company. - interesting projects I've seen other people work on.

## Feedback I've done some analysis on myself. Here's what I've deduced.

1. I suspect I'm too bubbly or enthusiastic. Maybe I come across as really young? I've been rejected from companies because I don't have enough experience. 2. Algorithms and technical questions are a bit of a chore. I'm weak at this. 3. I interview better when I express less interest. It's a little parodoxical for me. 4. Not going through my personal network. I am a significant part of 2 meetups, I should take advantage of that.

Can I get some feedback regarding this?
