Pros
I did an internship in spring 2013 at Entech and now I have been working in the company for almost two years. The experience I had so far is really positive. If you are looking for a great opportunity to learn and grow as a professional this is your place. Entech is a middle size company that is growing really fast. I have been working both, at Entech's office and at a client's office and both experiences have been really good. Working at a growing consulting company, like Entech, forces you to not to stay in your comfort zone and to work on a lot of different tasks and projects, which I consider a perfect way to move forward in your career. Everyone at Entech is really nice, helpful and close, from colleagues to managers, therefore the environment at work is very nice. Entech also organizes different cultural and social events which help a lot to get to know other employees that work in the field or in other offices and for team building. My favorites are the Christmas and Summer parties, but I also enjoyed a lot the monthly Friday lunches and the soccer team games.
Cons
I cannot think of any con at the moment.
