Pros
dSonic was the perfect first resume-builder. 1) Employer knows his stuff when it comes to creating unique sounds and demands a great deal out of you, forcing you to do your best. I would say I went from amateur to semi-pro in a matter of a couple months - excellent for someone still in college. 2) Because the company is a contractor who gets hired out all over the place, you work on everything from silly little facebook games to huge AAA titles, giving you a great deal of variety for your reel and your skills. 3) Co-workers are generally fun, cool people like you with a passion for games and sound. Trust each other for help and advice. 4) The primary piece of software you'll learn is Sony Vegas, which is surprisingly one of the easiest and smoothest tools for the job I've used. 5) Easy location to get to for college interns.
Cons
As awesome as the work itself is, the job is absolutely terrible. 1) Employer has little to no real respect for employees, their health, their opinions, or their lives. They are simply tools, easily replaced at a cheaper cost with free interns from the various colleges in the area. He has a very strong presence, and can easily freak you out with anger/disappointment, essentially ruling through fear. 2) Pay is very low, with no decent benefits and no hope of any decent raise. Pay is ~1/3rd of what most other sound designers in the industry make (http://www.simplyhired.com/a/salary/search/q-sound+designer), and as this company is in Boston, which is VERY expensive to live in, you will spend all of it just trying to get by. There is no pay ladder, it's more of a ditch. Health insurance was made mandatory in Massachusettes, which is the only reason you get any (though you still have to pay half the cost). There are no other benefits. 3) No vacation or sick days. While I agree with their personal mandate that 'if you're sick, stay home', as going to work sick just makes things worse...to literally force employees to stay home when sick and then not have ANY sick time pay is rather deplorable. 4) Setup is horrible for your health. Not only do you work almost entirely on headphones 8 hours a day (ear fatigue quickly became a frequent and painful problem), but the 'desks' are plastic tables and the computer chairs are cheap and not very adjustable, both of which quickly compound into a variety of back and arm issues. Proper ergonomics and long-term ear health are not even close to a top priority here. 5) Working hours are an extremely rigid 8-4:30 (do not be late or he will chew your ass out), so this can be tough for most college students who are not as creatively active until evenings. 6) To repeat the other reviewer here, the employer is incredibly stringent and ignorant about new technology, especially with software and plugins. Employer then complains when employees have a hard time finding new and interesting sounds.
