Tom Dixon interview questions

Had two rounds, with immediate manager and skip level. Very positive experience they were both very warm. But what didn’t go well is the communication. I didn’t hear back from anyone or HR after giving all rounds of interview and it being positive. This in my opinion is very wrong, no matter what the candidate should be informed of the final decision and why. I gave my considerable amount of time, preparing and giving it, the least we expect is some closure.
