Unprofessional behavior with no response from management - Anonymous employee Works Applications Employee Review

I am one among a group of around 50+ students who got placed in Works Applications last year(2016 Dec.) from various IITs/NITs, etc. First, they delayed our joining date till October. Now, they have changed several terms in offer letter: 1) Location which was earlier Singapore has been shifted to Tokyo. 2) They have suddenly decided to close two out of the their three divisions including a) Software Development and b) QA & Testing. due to which they have decided to increase the difficulty of the STM (training they provide in India for 3 months) and will terminate anyone with grades (B, C and D) after the training. Earlier, they used to terminate only people with D grade after STM. This is resulting in terminating about 75% of the employees (as they mentioned themselves) after training as compared to only 10% last year. They also mentioned that they may even terminate everyone in the worst case. At last, they have also asked us to leave the company before hand by taking the compensation for 1 month in case we are not satisfied with the above changes in the offer. We find these practices of the company rather unprofessional and would everyone in India to stay away from them.
