The 1st round is telephonic (every One will clear that) The 2nd round Machine Test They asked to implement JWT based registration process , I have implemented the full thing but there was no database installed on machine so i cannot save the token and verify the token . I called the interviwer and asked there is no db installed on machine , the guy said ok let me see what you have done , so he asked me where did u verify the token on login , so i told the is no db how can i save the token , So he rejected me . The process is very very pour , and the guy working on MEAN stack doesn't know Electronjs , i have doute on his credibility and knowledge . I will ask the management to change this person from talent hiring process.
