Absolutely terrible. Took 3 months and 3 rounds with final task as 10 pages detailed benchmarks of competitors and PLG strategy. After sending them docs, they never came back. I just became aware of the fact that the company is just collecting bunch of case studies and using them as a shady way of free service. Last mail from CEO was "Our team will now review your case study carefully. As a next step, after review, we will invite you for an online interview. JP van der Kuijl"
