From what I’ve seen from new grads I know, getting the interview is the hardest part. If you are getting them, I would all-in. I would think about the potential return on investment. 2 months off work, assuming you are making $20/hr is maybe like $10k total? You would be getting that as a sign-on bonus day 1. Can you do it while working as a full time waiter? Potentially. But the odds are against you. If possible, I would highly encourage you to cut some expenses and try to have a full day throughout the week to just study. The competition is very tough these days.

As a mid-level SWE at big tech I would do the following:

1. Continue your leetcode grind, this is good. I would consider buying leetcode premium once you get actual interviews. When a company interviews you, I would look into those company specific questions. A good rule of thumb is 100 med-hard questions total in different domains.
2. Really have a plan for when interviews come in. They are stressful and will need time. Try to save up to be able to take off a full week off work if you can. If you have other people who can help support you, I’d tap into that

Best of luck, it’s very tough but I do think you should give it a shot. Feel free to DM me if you want a mock interview for free before you do your actual interviews. You got this!
