I have been working at SEI Investments full-time (More than a year)
Some company pros are: availability to work from home if needed. Have a 401k with matching. Health insurance, vision and dental. Laid back for a corporate place. Company happy hours.
Some company cons are: long commute for most. The pay isn't great. Cant carry over vacation days and PTO, they are use it or lose it.
I applied online. I interviewed at SEI Investments (Philadelphia, PA).
I had a Phone screen first. Later I was asked for a face to face in house interview. Great place! Nice facility. Took long to hear back about the next steps. Very busy environment lots going on.
