Amazon tech screen experience incorrectly rejected

Hello,

I recently did an Amazon tech screen, the one where 30 mins behavior and 30 mins coding.

For Sr Engineer. (SDE 3)

I explained the solution to person in great detail and then started to code it but time ran out because I talked a lot. The interviewer agreed my solution as explained will work

I do think I had over complicated the solution to make it as fast as possible and that’s why I didn’t write complete code. I’m sure I would have passed had I submitted the leetcode solution. (Which I didn’t know beforehand)

I got an automated rejection email after a few days and it was no surprise. But what was surprise was that I got call from recruiter saying the rejection was sent in error.. (was a voice mail as I Didn’t pick call)

Now has this happened to anyone?????

Also I didn’t expect to pass the round without working code. I know the recruiter said SDE 3 your behavior and system design matter as much as coding compared to more junior roles where coding is very heavily weighted. I didn’t think it would be true as if I didn’t complete code it’s a 100% reject.

And a bit of a coincidence I did interview at Amazon and my tech screen back in 2016 was also heap question, top k closest points to origin. Which I nailed it. (Did terrible at on site)
