I just found out that I was rejected from one of my dream FAANG companies :(
The recruiter told me:
Thanks so much for taking the time to interview with our team - they really enjoyed meeting with you. Unfortunately at this time, we will not be moving forward with an offer. The team really enjoyed your positive demeanor, thought you had great communication skills, and a well thought out process throughout the technical interviews. I am not able to share specific feedback as per company policy, but I am of course happy to jump on a call if you have any questions.
What can/should I ask her in this call to maximize my learning to be a better candidate?
Sorry to hear that, I know it must be disappointing :(
Honestly, given that you don't get feedback, I wouldn't get too hung up on this. Interviewing is a numbers game -- the best thing you can do is just to line up a bunch more interviews.
Independent of the feedback from the company, you can also do some self-reflection. You probably know which interviews went well and which didn't. It's worth writing down some reflections after each interview and review questions where you feel like you struggled.
It's interesting that they can't share specific feedback, but the recruiter is also happy to hop on a call. Given that narrow target, here's some questions that come to mind:
As Rahul mentioned, it sucks that you didn't pass but every failure makes you stronger and you'll get it someday. Just keep improving and learning as much as you can. 😊
From my personal experience, sometimes recruiters are willing to share more direct feedback on a call than on an email. I'd definitely use this opportunity and ask specific questions about where you could have done better and where you failed like Alex suggested.
Best of luck!
