Tyler Petroleum interview questions

I had the worst experience with them. First they took an online coding test wherein they asked me to make a simple registration form and gave me an hour to make it. I completed it in 20-30 mins. After that they sent me a mail asking me for literally all my personal documents starting from my birth certificate, educational qualifications, all kind of ids, my pay slips and bank documents. When I asked them if I can show my pay slips after getting the offer, they denied saying they will make the offer based on my pay slips. It was really weird that they directly wanted to give me an offer after just one interview. I told them that I wanted to talk to someone from the team about the job role but I got no response. Then they asked me if I can join them in office in Kerala. I obviously denied given the covid situation but they said that most of the MNCs are opening now( which is literally not sure) and I should join them there and not waste this opportunity. I denied again and again asked to talk to someone about the role at least before deciding anything. After a few days, I got the offer letter and they had offered me HALF of my current CTC. I have never seen such stupid people in my entire life. They said because I want to WFH and didnt share my payslips before getting the offer, they have given this CTC. I rejected there offer.
