Serious issues with company - Senior Manager GEP Employee Review

The Job Profile will not be what has been discussed in the interview &/or match with the JD. They are targetting Managers & above and asking them to leave based on not meeting their expectations (just a tool used for sacking employees). If you are new, they will extend your probation period & then sack you based on not meeting the expectations. If you survive all of the above, you will be slogging daily 12-15 hours and will be working till late night which will impact your physical & mental heatlh. Please note this is going on with employees of all departments.
