I had interview a few months ago for MLE E6. I solved all 5 (including phone) coding interviews [all medium]. Their ML design was also super easy. The process took +4 months with a lot of re-schedules and cancellations without even notifying me. At the end, they down leveled me to E5 without disclosing the reason!!!! The recruiter said she cannot explain !!!!
Do NOT interview with this company until their recruiting system goes back to pre-covid when they were not outsourcing the coordinators. Their current recruiting system is HORRIBLE!!!! You will waste 4 months of your time preparing yourself for something that is not worth it! I interviewed with them in 2019 when everything was very smooth and professional. Right now it is a disaster!
