I applied online. The process took 2 weeks. I interviewed at Specsavers (London, England) in Feb 2021
Interview
Straightforward interview, take home task and sql test. Gone through the whole process and didn't get an overall feedback or answer. The company seems to be making use of ghosting practices to potential employees so be wary if you value your time
Interview questions [1]
Question 1
General retail related data science techniques: churn, clickthrough rate, a/b testing etc.
