I like how easy it was for me to find my project manager through up stack's website as well as their support team! They are very responsive and always willing to help you out with anything related to your job search or interview process. The only thing i dislike about them is there could be more options when searching other jobs/projects available at different time periods in order to better match everyone's schedule. If anyone needs any type of technical assistance regarding coding interviews then definitely reach out to this service because it will surely make things easier for you! Their customer service has been great so far and we have had no issues whatsoever!
