Tracxn Java Developer interview questions

unprofessional! Simple String program to check for wildcard(from given pattern) in a string, simple but whoever made it didn't think it through as there were cases which made no sense. After waiting few days without response i had to ask Tracxn if there's any update, their HR said this "We won't share the feedback with the candidates in order to maintain the integrity of our assessment process." I only wanted to know if it was my programming mistake or something else as i didn't clear the 1st round itself but I haven't seen such an unprofessional response, they said same thing again when i told i only need to know if i failed the question or is it something else but you see how they responded, choose the company wisely their feedback says more about them.
