After over 250 hours of studying since October, and doing multiple mock interviews a week, I'm finally starting to feel more confident in myself. I feel confident in the work I've accomplished over the time at my current company, and can think about it more critically.

It also helps to know I have my first "on-site" next week, have multiple technical phone screenings set up, and know that I'll be jumping to a new company sooner than later.

Studying really pays off if you do it well.
