I can only help with 3 and 4, but I'll do so. I've only been in the industry for about 5 years, but I've swapped company almost every year. When you're a junior, you rarely have the luxury to re-use the technical knowledge from one company when you jump to the next one. You'll carry with you the general development learnings, but specifics about platforms and domains are kind of thrown into the brain garage where they'll stay until you make an effort to dig them out. Now, you're not a junior. You have 12 years of expertise. These are worth a lot. Even if your specifics might not be as relevant you still have the general learnings. Of course you're not the best guy around when it comes to an area you're new to. Why are you setting these expectations on yourself? > When I see guys half my experience are miles ahead of me in terms of the tech skills in the new area, I wonder if I even have a chance catching up ? When it comes to your insecurities about this, just take a deep breath. You'll catch up dude. Everything's a process. Patience and persistence is all that's required.
