First stage informal interview followed by a take home assignment involving using the programming language of your choice to query an API and clean the data queried. There were a total of two questions plus a bonus question for the take home assignment which had to be completed in 4 days (approximately since I forget the exact time period)

didn't get any real feedback from interview (or anything constructive) seems like their HR department don't know what they're doing in the way of information or process. Disappointing for a tech specialist company...
