Pros
Some really hard working, talented people here. Most of them are also pretty friendly and helpful -- people watch out for each other here (at least most of them). The technology is interesting. The pay for the industry is ok. The benefits are pretty solid though. Work-life balance is good. Overall, I really enjoyed my time at Quallion and would recommend it to most people.
Kontras
Undesirable part of town. Though the company has many good people, there are some truly nasty, political folks who nobody likes (e.g. Director of Battery Development). As long as you avoid these folks you'll be OK. The new CEO was brought in 2 years ago to fix some accounting problems but unfortunately he knows nothing about batteries or the industry and the company's business/technology direction has floundered. As a result, Quallion has started to focus on the industry of last resort for every battery manufacturer: The Military. Most of the biz dev folks have also defaulted to this position for lack of any new ideas.
