I had never worked at a big tech company, and StellarPeers was my first introduction to that tech world. I spent a good amount of time studying Malena's practice answers. These were particularly useful because of their high quality, structure, and clarity. I also had about 20 mock interviews with other peers, some of whom became good friends, and shadowed the mocks of more experienced PMs. The mocks were invaluable because I could assess other people's answers, what worked and what didn't, and received feedback and suggestions on how to improve my performance. I also attended a few group and individual coaching sessions. Overall, all StellarPeers offerings were a great way to learn about PM interviews and Facebook products in a short period of time. Prep using StellarPeers was instrumental in my getting an offer from Facebook for a senior data scientist role. I have recommended the platform to others and definitely plan on using it myself again.
