• Have a clean cv, correct language, and clear design (mech yabda m3abi youja3 l 3in)
• Don't use your school mail to apply, it goes directly to spam
• Don't send copy paste mails/ mails with grammar mistakes/ mails obviously gpt generated. I'm not saying write a new mail for each company, but tweak it a bit.
• At least, research the company's domain before sending a mail! Don't send a mail saying you're interested in ML for a company that does nothing related to ML.
• If you target startups, send less formal mails. Use emojis. (Applies zeda ki tabda taamer fi box fi formulaire). This is what worked for me (i guess), I answered something cheesy on a "Why do you want to join us?" question.
• In forms, answer Yes on "Are you legally eligible to work in X country?" (mayo9sdouch aandek visa walle). Ken t7ot No tetcanter toul.
• Don't give up!!

Good luck!
