Meta Software Developer interview questions

I was interviewed by a new graduate out of school who did not seem interested in interviewing me. There was no consideration given to my experience to match me with an appropriate role by the recruiter or the interviewer. Overall, not a good experience.

Inside referral but got denied for multiple times without interview. Some months later, they just somehow remembered me and pop up and send me email appointing for a Skype interview. I am surprised they are trying to contact me with information on a years-old resume because I am sure I reapplied with the updated CV just some months ago. Interview is just programming online. Difficult as I expected. Few company come up with a DP problem at first interview. The engineer interviewing me kept asking me to change my algorithm. Managed to finish core algorithm, with potential bugs, and got denied (again) exactly 24 hours later.
