Recruitment talk first; they said no overwork (which I later found out was not true).

The interview took place on Sunday. It started at 9 am till 8 pm (for the interviewers; interviewees took much shorter).

At the interview, I was asked to fill out a health history form (very pretty HR girls).

I asked them about the overworking situation because they were overworking on the interview day.

They admitted that they do overwork, but it is special for the interview day. However, there will also be overwork when required to meet project deadlines.

Perhaps they discovered I found out their inconsistency; they did not offer me a second round interview. If there was one, it would take place right after the first round.

The recruitment talk said there is a wide choice of languages, but at the end, only Java programmers were needed.

Why Rakuten?

Why Japan?

Do you have internet programming experience?

In your Codility test, you referred to Stack Overflow for technical reference. What happens if you cannot find any reference help?
