Spikes are typically when a company shows a dramatic increase in job count. Spikes can occur when a company changes their Applicant Tracking System, and our spiders find jobs in both places for a few
days. This can be easily detected when a job count for a company appears to roughly double, and when it doesn’t stay at that level for more than a few days. The company scrape log exists to provide additional context around spikes and drops in the data. If a return to normal job count correlates with a scrape change, it can be inferred that the change in job count was due to a career portal change rather than an organic change in labor demand.
