Pros
There are some positives to Mujin of course. The staff overall is very intelligent and comes from strong education backgrounds. Mujin's products are interesting and competitive. Most people there are friendly and helpful.
Cons
I left Mujin for another company in the same field, doing similar work. I now wish I had done it sooner, because Mujin was my first job in Japan and I thought that the working style of the company was similar at other companies, but I learned I was wrong about it. I do not want to focus too much on the Covid situation, but for me this was really the thing that made me finally realize the company does not have our health as a top priority. At Mujin, the management did everything possible to prevent people from having any flexible working style during the pandemic (and this is still the case now from what I heard from colleagues). Only when the government in Japan issues an "emergency" status, the company would reluctantly send people home, but even then I could not do so without upsetting my team and my manager. Yes, some changes were made in the office to spread people out a bit. But honestly, when most other 'modern' startups (even in robotics) are strongly promoting and encouraging work from home, why would anyone want to stay at Mujin? How will Mujin expect to retain a top talent when their competitors have working styles that adapt to recent changes in our society. It's actually a little bit embarrassing when I tell my friends and family about this. They think I worked at a "black company". Even my spouse was concerned about me. I believe the HR and related departments had wanted to do more to improve the situation at Mujin as well, but the top management in the company has an unhealthy obsession with seeing everyone onsite and watching everyone and everything. I think this is ironic because Mujin designs autonomous robots, and one of their company mottos is to relieve humans of manual labour. I got it in my head that most companies are the same. After switching companies now, I realize that this is not "normal". My current boss, and his boss too place enough trust in me to work independantly, and employees are not pressured to come to office. Trust is a two way street, and I feel like giving 100% in my work thanks to the trust between us. Sorry for the very long "cons". But after changing companies, I felt like I had an awakening.
