I got two interviews and both times they said that I was unsure of my answers which I have no idea why because I answered their questions thoroughly and they even said I got most of the questions correct.

Initial phone call with a recruiter, he was really persistent regarding me accepting the offer, I told him lets go through the interview process first. An online exam that was about OOP and some SQL, I passed. Then a video interview was scheduled with a team leader, I answered all the questions. An offer was extended but the pay was extremely low, tried to negotiate but not much luck so I denied the offer
