The first code assessment was good because was general data structures algorithms exercise. The second one was kind of hard to fit all requirements in 75min without knowledge of the tech stack or code related before starting the challenge or information about the high expectations of the result or how will be judged, you need to finish the challenge and show a described result in a video in the expected time which is good enough if you are familiarized with the tech stack and unit test, but if not it is really difficult to fit the challenge in the specified time with high quality and following all standards related. Even though it was a nice experience and the recruiter was kind and communicative during the entire process, also a good thing is that they told you the salary you could expect at the end of the process.
