Hiring team called and setup an initial call with hiring manager, manager was positive and explained the role with details, I believe he was doing some exercises when he was talking in call or IDK what he was doing at that time. Later that day hiring team sent me an assessment to complete by 24hrs I did completed in couple of hours and sent back, after a day "without explanation they just simply said we are continuing with other candidates at the moment " I asked what is the reason but no response.

They reached out to me on LinkedIn. 3 rounds 1st Hr call went well. 2nd Technical interview went well. 3 rd Code assessment - take home assessment took me 3 hrs addressed all the criteria and submitted the output with the created code. But after a week HR updated me I am not shortlisted. So I reviewed the code again and asked them for feedback. He mentioned I missed to address the nested data fields. I updated the HR that the code addresses the nested data fields. Anyway the reason they gave me for my rejection was not very clear.
