There are 2 rounds of phone interview, if you pass these step you will be invited to an 4 hours onsite interview with group of Technical Manager, HR Manager. The onsite interview is very friendly, just like they want to test you if you can adapt to the working environment or not.

Two phone interviews and one day of in-person interviewing (with 4 groups) that lasted about 4.5 hours. The phone interviews were mostly technical questions and the in-person ones were a mixture of personality and technical. I probably would've said it was a positive experience if they hadn't waited so long (like a month) to send me a rejection letter. Besides the timeline, everything else was alright.
