Friendly, efficient, fast but irrelevant technical interview. In the job description, they ask front-end skill such as Js, ReactJS. But in technical interview, they will ask you to go down with infrastructure and algorithm before process to front-end questions.

I sent my CV through their website then a HR person sent me an Email to interview me. We schedules a meeting through Skype and we chat for around 10 to 15 minutes about my previous experiences, etc. It was a very basic interview probably for him to know me better.
