Gartner Data Scientist interview questions

The interview process was quick & till the point i was selected. After i was selected they started negotiating on my designation. This was also fine. Then i was told the I would get opportunity to work with IITians & IIMs. Great, as if i have never worked good & intelligent people. Still all this was fine & acceptable. Here comes the worst part: Finally, I was offered a position. My offer was revoked just before ~20 days of joining. This is during the coronavirus pandemic. Just 2 days back i was told about the joining date & then suddenly i was called up and told that my offer has been revoked. I completely understand situation of companies during this time. But a company as big as Gartner (which i unluckily thought was good) is expected to have some professional attitude & should take care of its employees and its "to be employees". If a company cannot take care of people in difficult times, it is not worth joining. It is the most difficult time for me.. where i am in the last phase of notice period, Gartner has refused joining. I can't even go and search for another job as all the companies have closed hiring.
