In all honesty, take a deep breath, relax, it's going to be ok. Now that you have done that, here is a bit of feedback. You seem a little scattered in your thinking. This isn't the biggest problem in the world. You need to just hide it a bit and look less scattered to your potential employers. Here are a few ideas: First, you have a PhD. This tells a potential employer very important details about you. As an interviewer I care very little about your thesis, about your advisor, and about which papers you are current researching. I DO care that you spent a significant amount of time solving problems. You found a problem, you stuck with it, and you solved the problem. Again, I have my own problems, I don't care at all about the problem you solved to get your PhD, just that you did! You have a HUGE ability to stick with things, this is an asset. Practice getting this out during your interviews. Make sure they know this is a skill they need within their organization and that regardless of the challenge, you will conquer it. Second, you have a lot of languages. There is nothing wrong with that, but tune your resume and your interview towards the one this potential employer needs. You mention that you study a lot. Spend that time studying the needs of the person you are interviewing with. Know a lot about their product, about their environment, and about their history. Be ready to talk to them about all of these things. Defend your "mini thesis" about this organization every time you walk into an interview with them. Third, practice confidence. I know this is easier said than done. I am not always confident in myself nor in my abilities. But I practiced and I show confidence when I walk into an interview. This helps a lot. Control the interview by asking questions, talking about what they need, knowing what to say when you get stuck, and showing your skills even when you feel nervous or scared that things aren't going well. Over the years some of my best jobs came from interviews that I was SURE I bombed miserably. Use your study time to practice these skills for a while. Never call yourself half as*ed again. Ever. Finally, practice interview questions! Google "interview code questions" and practice one a day. Practice them in different languages. Really understand why you use some of the techniques that you use. You have an AMAZING ability to study, learn, reason, and defend your ideas. Use these skills to your advantage. You will do well! Final Note: interviewing is a numbers game. You have to interview with a lot of companies to get where you want. You are already playing it well. Keep interviewing because you only have to pass that one best interview to get that one best job that you have been looking for. You can do it!
