Instructure Software Engineer In Test interview questions

First round was with HR and they go with their expected questions. After first round, they sent me an hackerrank link consisting of 18questions of which 15 were multiple choice related to testing and 3 were coding. Questions were from Strings, Arrays and DP. It's really tough to complete all three questions. I attempted 2 questions and multiple choices. I cleared the round and i made it to Third round. Third round was phone interview with Lead. He was cool and made me comfortable. He asked me basic Linkedin questions and asked me to write test cases for it. I think i did a good job, but other factors have played a role in my rejection. Received a mail saying "they're looking for much more experienced." Overall my experience is a mix of Good and Bad.
