The recuiter approached after I had applied for couple of different events. They found resume in the system and asked me for my availability. First step was an online assessment test, which was very easy. Then they flew me over to Washington for an on-site interview.
Onsite consisted of 4 interview round. 3 coding rounds and 1 OOP.
It was a recruitment drive, so the afternoon batch has 12-15 candidates and same for morning batch as well. The candidates were treated very nicely. The interview questions were easy to medium level from Leetcode. Focus on Data-structures and OOP.
