Feuji Software Developer interview questions

Two rounds of interview 1) round java related mcq questions 2) technical round Both rounds are elimination rounds polymorphism, exception handling , non prime numbers code , sql basic queries

I completed all rounds of interview process. They said You are selected and your joining will be within a week. After that they extended to 2 months of my joining date. After 2 months they said we unable to follow you profile because of recession. But they are taking candidates in jspiders institute inspite of taking us. This is totally unfair of this company.
