I like that they are very prompt in responding to emails or calls about my project needs/ questions! They also have good communication skills with their clients (which makes it easier for them when we need updates). Their customer service team can be difficult sometimes - but only because of language barriers if you're not familiar enough English / Spanish etc.. It's hard being able t communicate well since there isn't much interaction between client & us so far during our projects together :) So many things really! Just make sure your expectations match up wtih what YOU want from this experience before signing anything away!! We've been working closely wit hNineHertZ lately regarding an eCommerce App developed using Angular JS front end + Backend API written by 9 HERT Z.
