Pros
I've been working at Rakuten India for more than 3 years now and I absolutely love it. The people, culture, management, and work/life balance are all incredible! The company cares about its employees and goes above and beyond to create a positive work environment. Lots of room for advancement and growth within the company. Since this is a Japanese company, everything is based on trust factor. You get new projects from Japan based on trust, they interact with you based on trust. So, in order to build the trust, it takes time. For some employees, especially who doesn't care about cultural differences, this can be very frustrating and challenging. Even if there is an easy way to do things, you gotta follow the set procedure, but there is a reason for each procedure and once you understand it, you won't find any reason to complain. And once you're in their trust books, it's easy for you to interact with them and the Japanese will go to any extent to help you. You get to learn the real meaning of work ethics, principles etc if you really care to understand Japanese way of doing things. You need to have lot of patience. As every startups, there were initial hiccups, but now things have changed in Rakuten India and the company is on the ascendant: lots of growth, lots of cool new projects, tons of interesting work and opportunity.
Cons
If I have to say, there are few, but that's part of the fun, if you look at it the right way. So, I don't have anything bad to say about our growing company.
