I interviewed at Rally Health in 2018. There was an initial take-home assignment. After completing it, I was called for onsite interviews. There were four onsite interview rounds:
Leetcode-style problem-solving: This round involved solving a very easy problem, the Two Sum problem.
Leetcode-style problem-solving: This round involved solving a medium difficulty problem related to string manipulation.
System design: This round involved designing a restaurant booking system.
Behavioral round.
Overall, the interviewers were good.
