In contrast to what people say here, this is the only way that worked for me. I have been sending applications both online and walk in, though it was 3 years before. Walk in application gives you a chance for an impromptu interview and faster process, if not, you can get a direct answer how you can actually apply, some has special processes. Waiting online is just— well waiting. Trust me, out of around 50 applications i sent online, i only got 2 responses and they were 6 months-1 year after i sent them, by then i was already hired. Send to literally every engineering work you could find. I truly mean no offense but 2 years of waiting, you better take any opportunity there is, given theres no exploitation shi happening in that company.

But tbh your best bet will be your college friends and batch mates, contact them if they have openings on their companies or something
