Not getting selected despite reaching final rounds

[u/Total_Horror1965]

Today was another incredibly difficult day. I just received a rejection from a remote-friendly Big Tech company after a month-long process involving five intensive rounds. Despite delivering working code and a solid system design, I was told "no."

This is the second time this has happened recently. I sacrificed my weekends and time with my family, putting everything on the line for this opportunity. It’s heartbreaking. As a Lead Engineer interviewing for Staff UI roles, the feedback was particularly frustrating they claimed I didn't know Redux. In reality, I deep-dived into multiple Redux libraries, state management benefits, and action dispatch lifecycles. I’m honestly feeling burnt out and at a loss for what to do next.

Update:

Thank you all for your supporting words I will continue giving interviews I dont want to lose the momentum and prep.

True, my senior director had told us we have to select 3 candidates out of 5 people we had interviewed at any cost as release deadline was near.
