Interview process went well and they provided me conditional offer letter and even background verification is done successfully whereas no response after that. No response for my email from hiring team

Very Bad.. The recruiters are bad, dont get reply on the applied jobs. Interviews are conducted by Low experinced Guys. J ***Job description is not at all matched with the Intreview Panel Questions.*** The Interview Schedule is sent to 10+ people, The panelist doesnot have a idea/ plan why they are in interview.
