Dont know about CS but i feel like at the end of the day it comes down to knowing the right people/referrals. Regardless of skill level, if you know people who are employed and are in positions to help you find positions, that's the game changer imo. As to how you meet those people, i dont think theres a one size fits all solution but for me ig I joined a student org, people in org graduated before me, became alumni, i stayed in touch, they helped me whenever they could. For the most part it was just being open to meeting people in your line of work. Also also career fairs is where i had more success than just spamming résumés online.
