After the recruiter call, the first step was a coding assessment, followed by classic multi-round sessions evaluating your leadership in different aspects. The process was very long to start; it took 1.5 months to schedule the first interview. I do not know about the rest, as I did not pass the first assessment.

Implement in Java a MultiMap, a map where keys can contain multiple values, in 90 minutes.

There are two stages to the question:

1. Implement the basic methods.
2. Implement advanced methods like intersect, union, etc.

You must have everything done to qualify. It is very strict!
