I really love how this product has evolved over the years. Every time I have interview rounds going, I use product management exercises to refresh my mind on the best practices of nailing down the different interview rounds in the most efficient way possible. There is a decent number of interview questions that are categorized by type (such as product improvement or problem solving questions) and by top tier company. Most importantly, the community of PMs is fantastic, very helpful and very engaged which really paves the way for any PM to upskill and grow their PM career.
