I applied for a generalist programmer position, I got a call with a recruiter who then sent me a Node.js test (really specific questions). Really weird. Then I had a group call with 4 people, with varied technical questions. No code. Then they made me an offer, with a short reflection delay (5 days). I finally nicely told them I would not accept the offer at that salary, and would also need few more days to think about other aspects if my salary requirements were met. I have been told in a very cold way, that the offer was final and was not meant to be a comparison for other offers. I genuinely would have considered that offer if they made an effort on the salary, I don't understand this reaction. Very rude and clumsy.
