Ericsson is a good company to work for. The culture in the office is relaxed but can be very pressurised at certain times when big projects are on going. The management tends to be very hands on which is great. the hardest part of the job depending on your role would be that your are expected to put in the hours needed when their is a big role out on going which can then conflict with your home life balance especially if you have young children. the most rewarding part of the job was seeing your hard work come into fruition once the role out complete.
Ericsson for the first 17 years was a great company to work for. Unfortunately to the end of my time at the company the work procedures got in the way of actually doing the job and moral of the staff was negatively affected.
