I recently went through an interview process with Toptal, and while I initially appreciated the rigor of their screening, the experience took a turn that left me extremely disappointed—and frankly, concerned. During the interview, I was asked to solve what turned out to be a real business case involving vertical marketing strategy. Unlike typical interview challenges, this one required me to dive deep into budget optimization across several marketing channels: AdWords, Display, LinkedIn, and Organic. I created a working optimization algorithm to forecast performance and allocate spend across those channels efficiently, aiming to maximize returns within budget constraints. To my surprise, after I presented my findings and walked them through my high-level methodology and forecast results, they asked me to submit the actual optimization algorithm. This raised a huge red flag. Let’s be clear—this wasn’t a take-home test or a mock problem. This was a fully fleshed-out business challenge, and asking for my proprietary algorithm during an interview is, at best, unprofessional, and at worst, a blatant attempt to extract intellectual property without compensation. I refused to provide the actual code but explained how the model worked at a strategic level. After that, communication dropped off. They took my analysis and disappeared. In hindsight, this felt like a bait-and-switch. Interviews should be about evaluating skill and fit—not extracting free consulting work under the guise of recruitment. I would caution others, especially those in strategy, analytics, or data science, to be wary of processes like this. You should never be asked to hand over your intellectual property during an interview. Period.
