If you read the article, the main point was that Spotify doesn't inform about the limits clearly. Not the pricing.

I'm a hiring manager for a company in a regulated field. In addition to what has been said already, if a candidate came with a list of their own requirements for the said app, preferrably with unit tests, and/or a checklist of how much work there is still left, that would be gold.
The fact is, that probably all organisations deal with large legacy systems. If a candidate shows the capability to think a bit further than a tech demo, that's a huge plus.

Valitettavasti en muista liimojen merkkejä suoraan.
