First you submit your resume. They will make you take an online HackerRank assessment (3 leetcode style questions). The next part is behavioral, before you then move onto technical. (filler words to reach 30 word min)
I took a HackerRank exam that lasted around three hours. The questions were medium-level and similar to LeetCode-style problems. After completing the exam, I received a phone call from the recruiter inviting me to a technical interview.
