Rakuten Product Manager interview questions

Went through 7 rounds of discussions and case studies with the product, tech, senior leadership, program management stakeholders. Spent 12-14 hours on a case study related to their own business unit. Cleared all rounds of interview, but saw very clear red flags of the toxicity in the work environment. One guy glorified that people work for 18-20 hours a day for 6 months straight without taking a break. And the expectation from the candidate was the same. Most product team members were nice and it was a learning experience. But, the HR recruiter was very rude and unprofessional. In the end, they made a very lowball offer ( lower than my current salary), which I had to decline after a few rounds of review & discussion. This is after the HR knew my salary expectation on the 1st call. My suggestion is to avoid this company for this role, which will only waste your time.
