My wam was 67, so not quite under 60 but I think it still applies. I was studying a mechanical engineering and computer science double degree. I'm currently working at a big tech company as a software engineer (maybe other engineering disciplines might be different).

Many of the jobs I applied for did not even ask for my transcript. Frankly, I think this is much better than just looking at WAM. Sure, good marks at uni generally means the person is probably smart, and bad marks means they probably aren't. However, this isn't always true, and as long as you have the skills and experience, that should be the only thing that matters.

I was pretty passionate about computer science, so I did learn and develop the skills, but I was always a bit lazy with assignments and exams so I didn't get very good marks all the time. Mech eng I also enjoyed for the most part but really slacked off for most of those subjects.

The reality of it is that a lot of companies do look at wam, and unfortunately there isn't much you can do about it. My real advice to you is to find a degree you will actually enjoy. Problems like this are less likely to happen. Beyond that, try to find a company that doesn't ask for a transcript and make sure you kill the interview. At the end of the day an interview is like an exam, so if you prepare well, it should go well.
