I applied through other source. I interviewed at TrustingSocial (London, England)
Interview
Hackerearth test score 200/200.
On interview day-
Wait for 1:20hours till they can come back after lunch. No value of the candidate's time.
Then, a short intro followed by a vague question and left for 1:30 hour again.
Then, explanation of your solution.
Such a waste of time.
