Inexperienced management with poor leadership skills. Also, Rivian is so understaffed that the expectation is to work extra hours to make up for this with no overtime. They have a huge staff turnover as they burn everyone out. To check this fact out, look online and see the high number of ex employees from this company in its very short life span.
They have an unlimited PTO policy which means zero when everyone still works during their time off but that is to say if you are even able to take time off.
Health benefits are okay, nothing special and 401k is below par. Life Insurance however is quite good but short and long term disability is quite low compared to other companies in this area that are at 80-100%.
The office environment is extraordinary loud with elevator music playing all day and so many people speaking so loud, you end up with a headache at the end of the day. Many people in the office bring their own noise canceling headphones from home to wear all day to block out the noise.
