Interview
The interview process is very good and the entire process would be finished in 2 weeks. I contained three rounds of interviews each with pde3, reporting manager and director. Questions were mostly around arrays , dynamic programming. Stick with the basics and you should be able to clear it . There were some questions to design algorithm for the given use case. Hrs are very supportive.
