I applied through a staffing agency. The process took 3 days. I interviewed at Smarkets (London, England) in Nov 2017
Interview
The same day after receiving my CV I was sent an online HackerRank test by the Smarkets hiring team. A 30 minute practice test is available, and the actual test is 90 minutes long with 3 coding questions.
Within an hour of submitting my test I was emailed to let me know I had failed the technical test screening.
Interview questions [1]
Question 1
The input is an NxN array of integers representing depth level (higher value = higher depth). With an input of the form string[N], return an array of the same format with all 'cavities' replaced with an 'X' character, where a cavity is a local minima - all surrounding values (non-diagonal) must be a lower depth.
