I received a call from HR for an initial screening, passed it, and then was given a 7-day assignment. I completed and passed the assignment test. After that, I had another initial screening interview with a person from Singapore, who rejected me because I didn't know the business language—a detail that had already been discussed in the first call with HR. I suspect that the interviewer was xenophobic, which influenced his decision. Normally, the process includes an assignment review after passing, which didn't happen because I was put through initial screening again. It was kind of unfortunate for me, but a big no and a waste of time.

There was an assignment in Scala to transform the data and answer business questions from the data.
