I told you Sir, It was my first job change. I did not knew the tricks of the trade.
Yes, I have myself to blame because I trusted the people involved in hiring from one of the top 5 tech companies in the world. Id did not occur to me that I am being played upon.
However, If you had noticed, I mentioned I argued with hiring team [ PM, director, recruiter] IN WRITING BEFORE JOINING THE COMPANY. I still have those emails. As a response to those they used to call on phone, NOT reply in writing. It was evident to me that they are calling back because they have read the emails. I forgot to take the same thing in writing, because I trusted them.
So, Yes I joined them because of verbal promises, but the emails do exist still, in my mailbox, where I have asked them in band pay, before joining.
Initially when I approached the company's authorities they said " I am making this stuff up", but when I showed them emails from my mailbox, they switched to "since you do not have replies, ... .. .. you do not stand a case"
