Shield AI Embedded Software Engineer interview questions

Screening interview with HR followed by HackerRank coding test. The HackerRank test consisted of 4 questions, 1 very easy, 2 barely legible, and 1 that actually gave no instructions. I had 90 minutes to complete these, and a good 45 of those minutes were spent trying to understand the problem statements. The worst part was that none of the questions were relevant to the job I applied for. Like many of these terrible online coding exams no partial credit is given.
