Pros
Wizeline is the best company I've worked so far. I've been working at Wizeline for more that a year and my experience is very positive. You get to work in such amazing projects that require the direct interaction with different departments such as Sales, Marketing, Customer Success and also you work directly with the client. That gives you a lot of communication experience. You can also work with cutting-edge technologies such as Amazon Alexa to develop skills that impact directly to millions of users. The most amazing thing about Wizeline is that if you don't know a technology in a project they help you learn it so you have a comprehensive experience. Also, they give you the freedom to learn new things and work on side projects that help you build your career.
Cons
Since is a fast growing company, somethings will be overlook but don't let that slow you down. I don't have any problems with the rate of growth the company has. Actually that helps me to learn new things around working at a startup.
