Target Software Engineering Manager interview questions

Process was very organized, interview with recruiter, interview with the architect, technical case study. First two interviews went well,but choked on the third one. I was given 3 problems and asked to create a program in any language and upload to slack, did that but I feel it did not go well. I openly agree that I was busy and did not finish the code according to my standard so am not surprised that I fail, well, good experience.
