I applied through a recruiter. The process took 6 weeks. I interviewed at 2K (Dublin, Dublin) in Oct 2020
Interview
Started out with a screening interview,
Followed by a take home task in segmentation.
Then followed by 2 separate technical walk through of task.
Final round interview with Manager and also HR.
Felt I was misled throughout the process. I was told I did great on the previous stage and that I was through to next round, yet when it came to the crunch at the end there was no offer, and no concise feedback why. Overall, a very unorganised interview process.
