ManekTech Software Engineer interview questions

Before Interview , I have already told them I have one offer in hand and package amount is this. If you are ready to pay more then We can schedule interviews. Hr team agree with the condition. After that I have cleared all three rounds and they offered me very less package. Total waste of Time

First i got a call from HR and she arranged an interview. I cleared the technical round which was like a QnA. second round was assignment round in which they gave me an assignment but unfortunately i was not keeping well and told the HR that i will submit as soon as i get well. She was cool with everything and the assignment was delayed. After working on the assignment for like one n half day i submitted it and asked for the result she didn't reply me and then on monday also i texted her for a reminder. So easily she said the assignment was not passed. I don't believe her because putting so much efforts and doing all the stuff assignment was rejected. If they were not accepting late assignments she could have told me why to do such stupid thing.
