I will be forever grateful for StellarPeers as the videos were fundamental to my practice of the interview questions, which ultimately resulted in an offer at Facebook.
The key to cracking a PM interview, is to practice mock-interviewing. I practiced regularly on StellarPeers calendar and it helped me internalize all that I read in books and learn so much more from the techniques, ideas, mistakes and experiences of other candidates. It did give a boost to my confidence for the D day. I definitely recommend StellarPeers.
I benefitted tremendously from the private coaching sessions I booked with Malena. I followed her advice religiously. She gave me detailed guidance on which resources to study, especially for coding and system design questions. I got excellent feedback from my interviewers at Google, and that is a big deal for me as the bars are really high there. Malena gave me precious advice for estimation questions, and following her guidance, I became so fast in doing estimations no mock partner could believe it.
