HR interview, technical interview, assignment and another technical interview. It's not hard, cover basics to advanced principles of the programming language. They are polite, and no one is rushing you. Assignment was to use their API to build and app, which wasn't hard and plenty of time to do it.

The interview was very pleasant, First of all there was an HR interview where they introduced the company, projects and other processes, where I had opportunity to ask both technical and company related questions. Couple of developers joined the call asking basic questions about your experience and project you worked on followed by couple of technical questions. In the next step there was a technical task (may vary depending on applied position) for which I had a week to complete. For front-end position there was an Angular project to integrate with their existing APIs. Last step is a technical interview where we discussed about previously completed task and they asked me how would I solve some other coding problems (e.g. architecture of facebook feeds page).
