Disappointing Experience – Strong Performance but No Offer Despite Positive Feedback I recently interviewed for a Network Production Engineer position at Meta (London). The process included a screening round where I successfully solved both coding problems: • Problem 1: Battleship problem. • Problem 2: Reading a file and finding repeated occurrences of words, along with explaining time and space complexity. The first technical round covered networking fundamentals (TCP/IP, basic network topology, H-S-R-S-H communication, packet drop analysis, TCP flow control, and congestion control). I performed well in both rounds and received positive feedback from the interviewers. However, five days later, I received a rejection email, stating they were “moving forward with other candidates.” Seeing the same position reposted on LinkedIn shortly afterward was frustrating and disheartening. When I asked one interviewer about Meta’s work-life balance, his response felt dismissive and unprofessional, which added to the negative impression. Advice to Management: Please provide constructive feedback to candidates and maintain professionalism during all interactions. Transparency in the hiring process would improve candidate experience significantly.
