I joined a new company 1 month ago. This company has code which spans over 19 long years. It's a big company and the code is great without a doubt.
But when I am told to work on a task to do, say, XYZ, I have to dig deeper and deeper in an ABC file which is always more than 7000 lines. (The whole project code spans over 2,00,000+ lines.) And inside that ABC file there are lots of calling to outside methods which are in another file, say, HIJ.
So sometimes as I am new and it's a huge learning curve, I feel low. I mean it. It really makes me sad and reduces my working ability to ace as I used to in my previous organization which always had medium service-based projects (current company is a product-based one).
