Tripeur Front End Developer interview questions

This organization has poor management. I cleared all technical rounds and when I contacted them for feedback suddenly they kept my number in block. This shows their behaviour not less an animal . feeling shame on this organization. Team lead who took interview dont know much about the technical, still think who had hired him as it seems like empty brain only know the interview questions and answers. Still thinking who had funded to this organization. I request them to change the worst behaviour and have some respect towards the candidate who used to come for an interview.
