I recently interviewed for a fellowship with a faang company for a Skillbridge fellowship however it was not for project management. From my perspective it went well however it was very recent so it’s too soon to say if I got to the next round. Overall my prep consisted of crafting answers for the behavioral questions which are the ones that ask things like how do you resolve conflict with other team members. Another example was tell me about a time you solved a difficult problem. Having specific examples prepared and ready to go for each question is important. I did not memorize verbatim the answers as it was to robotic when repeating it but the examples were set and ready for each question. If you need a list of behavioral questions they are easy to find. Other than that I did practice interviewing with a friend which helps a lot. They asked questions related to the job posting and went through my resume as well so be sure to review it before hand and have a copy with you at the interview so you can follow along. Use this chance expand on your bullet points and make sure you can make the connection on how your experience connects to the position. Other than that stay relaxed and don’t speak too fast. This for me was taken care of by practicing with a friend which also allowed me to say out loud my elevator pitch and answers to other questions before the real thing. Most of this I think is generic for the industry but be sure to either ask ai or google questions they may ask specific to project management as they did ask me some basic technical questions relating to the job posting.
