Rakuten Human Resources interview questions

The whole process was smooth and interviewers were professional. At the first stage was a test about some simple math, English, and your knowledge about E-commercial. Then I had a talk with the recruiter. Couple days later the recruiter called me for the second interview. The second interview was with the lead of the department, who was also rather professional and kind. The whole process was comfortable.

Was scheduled for an on site interview that was cancelled with no explanation and was not rescheduled. I have not received any updates nor rescheduled for the interview.
