Those wanting to work for WibiData better have impeccable Portal problem solving skills. Part of the application process for the San Francisco tech startup involves completing a custom level, based on the company's offices, says the New York Times.

A teaser of the custom level can be seen above. WibiData, a computer engineering firm, created the mod as a test for new applicants. The company's CEO said that playing Portal (and Portal 2, upon which this mod is based) he felt the game challenged his reasoning in the same way as a complex programming problem.

WibiData commissioned modder Doug Hoogland to create the level, which features WibiData's offices and a secret (nonexistent) test laboratory beneath them. Hoogland, notes PC Gamer, came to WibiData's attention after he built a wedding proposal mod in Portal for a customer of WibiData.

The level is available for download at WibiData's website.
