It was a 3 round interview process with 2 technical rounds and 1 HR round. I was mostly asked DSA focused questions. Trees, heap, graphs and sliding window were mostly stressed for me.

Question 1
Trees, heap, graphs and sliding window were mostly stressed for me.
I applied through college or university. I interviewed at YouTube in Oct 2014
Interview
I was contacted about a month later after career fair, and was scheduled for a phone interview. The recruiter was quite professional. I was asked about general data structure questions like what is a hashmap, the time complexity of operations of hashmap and bst, when you prefer bst to hashmap, what is java gc. Then I wrote a small program to remove duplicate strings in a file on google doc.
Then I received a call from recruiter next day telling me to prepare for an onsite interview.

Question 1
generally not hard. you have to be clear with basic data structures
I applied online. The process took 2 months. I interviewed at YouTube in Oct 2024
Interview
Long and slow. There were four rounds of interviews spanning over a month and they don't get back to you quickly. The interviews themselves were ok and took an hour each.
The interview process was demanding as they asked several questions about my masters degree thesis and on my research projects, which were challenging to remember as I had done these more than 7 years ago.
