Pretty much the same process as everyone else. No human interaction whatsoever.

I applied online and received an invitation to the logical test within 12 hours. The logical test was easy at the start but got harder towards the end.

The day after that, I received the invitation to the online assessment. I had 3 days to start it but only 2 and a half hours to complete it. As I was busy that weekend with a midterm, 2 assignments, and tutoring, I emailed them asking to push the deadline back by one day but got no response.

The OA had the same 3 questions as everyone else: the longest valid password in a substring, the elevator question, and the 2D array countries question. I got all of them right, but I guess my scores (assuming my complexity) were not high enough, as I received the rejection email the next day.

Given a 2D array filled with integers, any adjacent element (vertically or horizontally) with the same integer is considered a country.

Return how many countries exist in the given array.
