Then after putting my lot of time and efforts when finally it comes to release the offer, then they stop picking up the calls and stop responding and the final excuses which I got from them for not releasing the offer is that their software will not allow them to release any offer which is more that 2 days of joining.
Such a pathetic company who even don't know that atleast if you are not releasing the offer, it's your duty to atleast tell the person that either they are not able to provide the compensation as discussed or they are looking parallelly for someone who can settle in less compensation.
Due to all this I have wasted almost my 3-4 weeks of time expecting that I will receive the offer, and didn't focus on other organisations which was ready to provide slightly lower than this.
Hence it's a total scam which is going here suggesting not to get trapped otherwise you will not only waste your time but also other good opportunities as well.
It's a total boycott for me, expecting the same from your end as well, so that they will understand that playing with someone's job is not a joke.
