When I finished my studies, I was looking for a job and had an interview at a smallish company.

Boss: can you do C?
Me: yes, I have already done some stuff in C.
Boss: I mean, are you really good in C?
Me, growing suspicious: well yes I already have been using it - but anyway, there's also the project documentation for looking up, right?
Boss: uhm, the code IS the documentation.

I envisioned myself being drowned in undocumented spaghetti code and wasn't really keen on that job anymore, but my following question pretty much ended the interview:

Me: oh, I see. Do you have any roadmap for getting your development to a more professional base?

His looks, priceless! He was just shocked when he realised that he had failed my interview, and that I was a fresher made it even harder to digest for him.

Rare photo of me explaining how close I am to pushing my code to production at 3am.

I recently joined a new company where work is quite different than my previous company.
Every day at work is challenging for me. There is good exposure to learn technology in depth. But time constraint to deliver module like under 3 days does not let me learn my work, also I am not satisfy with the quality of my code that I provide, it more looks like a patch. In my previous company I was favorite developer of my team but here I feel like a fresher who doesn't know from where to start.

Even I feel like my presence does not make any impact in office as I am just like an extra player of the team. I am slow at my work because I learn then I code due to which my manager does not consider me for any new work. I feel like left out in my team.

Once I overheard one of my colleague he called me helpless and were making fun of me. With every passing day I am losing my confidence.

I have no github reputation. It's like I am jack of all trades but master of none.

Every day is like big fight day in office.
I know our only way to survive in this industry is to keep on learning but in smart way. I am not sure what's that smart way?

Any advice would be helpful.
