Just giving back since I got a lot of help. I'm a new grad with less than a year of experience.
I honor everything I signed/agreed so there won't be details about the questions. But, Ill give you my prep path that made it easy for me. I think this is better than actual questions anyways.
Quick intro then coding questions. Array related question. - medium String and hashmap question + some follow ups - medium
Next day I got an email about an onsite invitation.
After 3-4 days I received a verbal offer. My recruiter and all the interviewers were super nice.
Previously I failed interviews at Microsoft (twice onsite), Bloomberg (onsite), Amazon (onsite), Lyft (phone), Airbnb (onsite), and a couple of really good startups who got funded big $$$ recently.
So yeah, that's normal. I am not a genius as you can see. I have been practicing on and off and only recently got better honestly. I like developing applications not doing these coding challenges.
I am very happy to join Meta! Thanks again and goooooood luck everyone!
