I applied through a recruiter. I interviewed at Barclays (London, England) in Jul 2018
Interview
One month after a take-home exercise and an on-site interview I was told that the role was assigned to someone within the organisation as a promotion. So it seems I was invited for an interview to fulfill formalities whilst the management promoted their crony. Very unethical to say the least!
Interview questions [1]
Question 1
There were questions about statistics, machine learning, etc. The usual stuff a data scientist is supposed to know.
