So many, but the most important by far is that this is a place that is driven by sales, not reality, so be prepared to work long, long days, into extreme times of the day, and on the weekend. Absolutely no respect for work/life balance. Managers just shrug and mutter that their hands are forced (and they likely are) so work we shall.
Connecture is very into outsourcing and this means that you often are working very late or very early to "hand off" your work to colleagues across the world. Why wouldn't you just work on your item the next morning and the offshore folks can work on theirs? Because every feature is born behind schedule and they need to close them out as fast as humanly possible. Development done via the game of telephone. The quality, predictably, is atrocious.
There's another reason quality is abysmal. The teams that customize the base product for clients have a zero unit test policy. This is not a joke. The theory is, because client implementations are dependent on OVERWRITING the code written by the core product team, we would have to change unit tests whenever the core product code changes, so it's not worth it. The way things build by swapping out classes at build time also means you cannot meaningfully refactor things. This leads to a solid majority of your product being classes that have thousands of lines of code each, with a decade of skeletons built in that nobody can clean up.
While the way employees are treated are awful, I have to say the people who suffer the most are our offshore colleagues. Connecture treats them like they are unimportant property telling them that they have to work enormous hours at times when they should be in bed or with their families, and this is done for months and months at a stretch. On top of that, they are also the first people that they brow-beat for our issues, when it's all of our responsibility.
Please, PLEASE avoid this place like the plague. It's a nightmare factory at any pay range. I've done two tours at Connecture after being promised that they as a company have changed. And they have, just for the worse.
