However, you get a biased sample with obvious rock-stars quickly finding a job. Thus, negative signs on a resume are positively correlated with candidate quality. On the other hand resumes that look great are likely linked to people who regularly fail interviews.
PS: This is less common with collage job fairs where you get closer to a random candidate selection.
Or even more simply, just use your eyes. The superior line breaking algorithm is extremely obvious, with or without microtype. Then less obviously, look at ligatures, kerning etc.
I don't care for the rigidity of Latex and don't want to hand craft my own TeX documents. I once had a resume generation system that would convert ReST to Docbook and from there used XSLT to produce plain text, docx, and PDF output using XSL-FO. Sadly the code was on a failed Seagate drive and is lost. And yes I had a backup, also on a Seagate drive that also failed due to a firmware bug around the same time.
You CAN get fancy with LaTeX, but I doubt most people will be doing those things. For every day research papers or resumes, just pick up an online template and make whatever minor tweaks you want. Then fill with text.
Perhaps this is selection bias?
Their resume being bad caused them to not be able to get a job at other companies, even though they are good. The only reason the resume ended up on your desk was because nobody else wanted to spend 30 minutes of their time interviewing them, therefore they were passed up.
Originally I had a similar conception about résumés — they should be one or two pages max, should look nice, and should contain no errors. For obviously this indicated a candidate who cared about how they represented themselves. How could a candidate with a slap dash résumé be any good?
But time and again the better candidates had the worse résumés ... résumés that were pages long, or completely unformatted, or filled with errors. Perhaps these candidates with poor résumés have simply prioritized their time on their work, not tending their résumé. Or perhaps they feel that they should be judged on the content of their résumé and not its presentation.
Regardless, I no longer put any stock in how a résumé looks, only wheter it indicates an appropriate background for the job.
