Ever since Facebook Messenger opened up towards modifications, chat bots have been added by various developers. Some of them have simply been for fun and frolic but others have developed useful applications. For example there is Job Pal, which is helping out with talent recruitment. Random questions are asked to users on the premise of networking but if the conversation goes well, a job offer is made right on the spot. Several companies have been enlisted for such services including Uber, PayPal, Citymapper and Hailo. There have been some failures in related organizations such as at Microsoft.
