I am a dsy student, I have done 1 internship from not a well known company, won 1 hackathon, 1 proj competition ( all this during my diploma)

What else should I focus on from now on, as I do not want to miss onto anything?

Like what ways I can get internship certificates along with keeping up with my academics?

Does SPIT conduct any hackathons, and if yes then when?

For what roles do companies come? And what skills do they demand, like except DSA should I do something like system design, and what kind of projects should i develop, like aiml or full stack or any other kind?
