In this all process they even not enclosed the salary. 4.They gave me A auth0 api to bind the value which was cors enabled and they even not told me about that it is cors enabled. i completed my work on first day itself . but APi was not working in code and was showing error of cors enabled headers 5.As a fresher no one would know what is cors but i done r n d and came to conclusion 6. they told me to u r not selected and please submit your code . if i m not selected then why would they need my code. actually they were trying to complete task with my help and would never call me baCK. very much disappointed companys are exploting fresher at such level
