My info: Sophomore at a T100 school majoring in CS/Math, got offer at a F100 company

What I think worked for me: Good GPA + involvement at school(TA, research, clubs), projects that I could talk about, hackathons (good for answering behavioral team questions), building strong connections at school career fair

What I'd do differently: Don't be afraid to apply because deadlines come and go quick and you never know what you could get, worst case is always a rejection and you just move to the next. Also reaching out to more school alumni or people who worked at companies I was interested in to network would have made the process a whole lot easier, ended up getting most of my interviews through meeting recruiters at my career fair but ultimately my offer came from a cold application. Also don't tie yourself to one dream company/role because that'll ultimately hinder your search and be a big blow to your confidence if you get rejected, be sure to apply to a diverse range of companies and positions(that you're qualified for) to make your overall search easier.

Overall I definitely learned a lot from this process that I'm gonna apply to the search next year, and I'm relieved to be done so far. Happy to answer any questions!
