Pros
It is very fast-paced and international. You get to work with different clients and travel. If you like to travel, then you might like it for few months or years (Please bear in mind, only if you work for PCO, Ovation or Association Management in event production role). The average working age is around 24, with only senior management being over 40. This mean that is rather fresh and innovative place to work. Many people are genuinely interested and care about their clients. The management does not give too much opportunities for training, but there are some group initiatives, such as Dream Day (admittedly, not too impressive initiative). Also, very open and tolerant: lots of women in high level positions (minus the CEO) and openly supporting minorities and different cultures.
Cons
Expect to work for more than 3 client. Expect that you will not have regular 9 to 5 working hours. Instead, you will be expected to work minimum 10 hours a day, sometimes 7 days a week. The overtime will not be compensated in monetary form. If you are lucky, you might get one free compensation day. The managers are too busy to provide supervision and direction to their team members. The directors are too busy getting more projects to fund the company and its board than providing support for the managers and their teams. A lot of gossiping and bad mouthing because of bad atmosphere (that is caused by anxiety, stress and overtime). In addition, the company is going through restructuring, and there is a lot of uncertainty in the air. Be prepared, if you do not deliver and a client complains, you are out. There really is not a lot of security. In addition, the business development team sells the people and their talent with a lower price than the projects require. Thus, the employees have to bear the responsibility of bad management and business development decisions.
