Spring is either scamming candidates to get ideas/work for free, or dropped the ball in the worst of ways. I reached out through a referral and they asked me to apply online. Once I submitted some example code and writing, they asked me to answer some technical questions relating to a small data set. Weirdly (and this may have been a red flag) they said that I had been selected as a finalist for the role solely based on this and without ever having talked to anyone on the phone or in person. They had me sign an NDA and sent me another technical problem to solve, this time a with real business application. I submitted my work, they thanked me and said they were excited to meet me. Then it got weird: after no communication for weeks, they apologized in an email and said the chief scientist (who was hiring for the role) had to leave the country for a personal matter, but that they would get back to me in a week. Two weeks went by before I finally reached out too him directly then to my referral contact. Neither ever replied. What I take from this experience with Spring is either they wanted work done for free and were never really interested in hiring, or they were stringing me along for lack of organization or decency. Either way, Spring is very unprofessional and unethical.

One recruiter Phone screen ,one sql table and coding exercise. Analytics focused, One ml thought experiment with technical product focus , one hiring manager review, 1 product stakeholder interview, sometimes leadership sign off interview.
