I need your help. I am desperate. I am worthless.
Last year, I failed my Google STEP and Microsoft interviews. This year, I failed another two interviews at different companies. I have a problem with problem-solving. I don't know how to get better at it. I don't know how to make an interview practice roadmap. I don't know how much time should I dedicate to become better within 3-months period. I don't know how should I track my progress.
Please help me I already hit the rock-bottom version of myself and seriously need your help guys.

And comes the important question: Is there ever hope for a third-year computer engineering student who sucks so much to become a brilliant problem-solver?
I already feel I ran out of time. I hate myself and all the time I had wasted in the past two years.
