I had an initial 30min interview with HR with standard questions. As a second step I received a case study with 2 tasks: 1) Prepare a Commercial analysis of the market where Lingoda operates ( including market overview, market segmentation, vendor comparison, go to market strategy) and also an analysis on Lingoda's positioning and future strategy. 2) a P&L projection for the next 5 years (I received an excel file with some data). And their request was to make a presentation of 20 pages. I have worked in consulting, I know how to structure a task like this and of course I have a deep knowledge of powerpoint&excel. I have to admit that I could have submitted a much more detailed analysis/strategy but obviously I stopped at a high level analysis because my goal was to demonstrate that I have the skills to do a similar job, not to provide them with a presentation for free. The feedback I received was incredibly superficial and not very detailed. In my opinion, this was a very bad experience and I even have doubts that the process is aimed at receiving free work from candidates and not to select potential new employees.
