Stage 1 - 30 minute call with recruiter. Stage 2 - 30 minute call with hiring manager to discuss background and skillset. Stage 3 - Take home challenge, took roughly 2-4 hours to complete with an extra hour for quality checking. They ask you to integrate a LaunchDarkly feature with an external software and provide a mock customer response outlining the solution. Stage 4 - 3 hours of panel interviews with 4 different topics: manager intro, homework review and growth/coachability, technical assessment, culture and values. I was told I did well in all my interviews however an offer was made to someone else. I can confidently conclude it was a well planned interview process and I felt everyone I interviewed with valued my presence and asked great questions to truly find the suitable candidate. I never felt like I wasn't being taken seriously and did not feel discriminated for my age unlike in interviews at other companies in the past. A few days after the rejection I received an email stating they were impressed with my candidacy and I was invited to a private vetted job platform used by their VC investor with a positive referral. Which is something I have never seen before and seems like a valuable addition to my job search so I am very appreciative of the referral. I would happily interview at LaunchDarkly again in the future.
