I interviewed for the NA internship position. I went through two interviews, then an additional one. I reached the host matching process but failed to find a host. I was referred to Sydney and received the offer.

Very good. Nice question. To excel, you'll need expertise in LeetCode exercises, a solid understanding of algorithms and data structures, and proficiency in dynamic programming. It is also important to know computational complexity and graph theory.

I was contacted by an internal recruiter and went through a phone screen and an onsite interview. The recruiter was very kind and helpful. This was my first tech interview, and I felt I was treated very well, even though I'm not quite ready.
