Twilio Work Experiences

Great place to work, terrible management

Software Engineer II • Current Employee

Pros: Great work culture where you're the owner from start to finish of everything you do. Great culture, open to cross-functional collaboration, and someone is always eager to help you in any way you need. Great place to learn and grow your career.

Cons: There is a level of bureaucracy impacting your delivery of full projects, and sometimes it's very hard to do it, taking around 7 months from start to finish for a very small project. Direction is very poor, and the high-rank direction do not follow the same culture values they so proudly announce. They change direction every quarter and dispose of people without thinking twice. Consistent layoffs every 6 months, handled very poorly.

Pros: I like it a lot since he has many years of experience. In addition, they have a very well-established career path, as well as many other things. The spirit is super great and people are very open to helping you from the first moment. It is a company that does follow its values.

Cons: It is complicated at first, as you need to adapt to the multiple time zones. However, they make the best effort to have a good balance with your life. It is very sad though that in just a few months, we lost a lot of peers because of layoffs. However, I hope the situation becomes better.
