Rakuten Software Developer interview questions

Started with a simple coding question (Leetcode easy) done on a google doc. The attached interviewer/engineer will also probe for your thought process and any improvement to your solutions. It is then followed up by a friendly background interview asking about your past experiences and projects.

received a technical test via email, then I was called few days later for a screening call with HR, and had an interview with 2 senior senior engineers this took 2 weeks
