Data analyst sollicitatievragen

Zoals gevraagd heb ik een 10 minuten durende presentatie voorbereid en gegeven. In deze presentatie heb ik mijn visie gegeven, echter aangezien ik de organisatie intern niet ken, kan ik niet aangeven of deze visie revolutionair is of reeds "mainstream". Deze naar mijn mening gepaste positiebepaling koste mij uiteindelijk de baan, aangezien dit als "niet commercieel" wordt ervaren. Naar mijn mening kwam de evaluatie van de presentatie niet overeen met de gestelde doelgroep (collega's in plaats van klanten).

with the CAR or STAR algorithm

They assumed that the services supplied by out-sources is as good as that of in-sources (FALSE) and that the customers are equally satisfied from both types of employees (FALSE). With these assumptions, they wanted to point at seasonalities in the time series of the received complaints. That is, they suggested that the time series of incoming complaints was trended (because the company is expanding) and presented seasonal behaviour due to holidays, big events and so on.. My "too money-oriented" answer was to manage the increasing trend with in-sources and to manage seasonality (even daily seasonality) with out-sources.

Not sure of the answer but would try to partition my query.
