Meta Software Developer Internship interview questions

Phone interview with an engineer located in Mountain View. Contacted directly by a recruiter in Boston and scheduled an interview with an engineer elsewhere. All correspondence was efficient and friendly, the engineer I spoke to was receptive to questions and even somewhat critical of the company which was a pleasant surprise.

Phone screening where I was asked to solve write two codes on a notepad. I solved the first but struggled with the second. The interviewer was very helpful in helping me write codes.
