Ramp Software Engineer(Internship) interview questions

I came across an opportunity online. Prior to submitting an application, a prerequisite is to tackle a CodeSand challenge. This challenge comprises fixing five bugs, after which you're required to provide the link to your solution in your application. While the bugs weren't excessively difficult, I invested several days to address them. The company opted to reject my application without offering any insights. Such disregard for people's time feels truly disrespectful. Please, Ramp, you NEED to improve your interview process.

First a 30 minute phone screen and then a 1 hr technical interview, from what I was told there are basically 3 technical rounds throughout the entire process. Was told my interview would be for frontend but did not end up getting a frontend question, which was confusing.
