Here's another explanation. My hypothesis goes deeper than gender imbalance.
Most job interviews are theater nowadays. It's about conformity, performative culture fitting, agreeableness (read, willing to slave away without complaining).
On average, women tend to better suited for such processes. Along with immigrant groups.
Women are taught from a young age of how to engage with their role in a patriarchal society. This includes caretaking, nurturing, and having patience for men. It's not uncommon for young girls to be given household chores that they must "suck up" and do while they're brothers get away with not doing chores.
In addition, we associate politeness and pleasantness with femininity. A woman ought to be kind and softspoken, and must not swear or raise her voice. We associate masculinity with abrasiveness, stubbornness, arrogance, and rage.
In most jobs and, in fact most social processes, the former is more useful to take advantage of. This could be why women, on the whole, would do better in interviews.
In addition, it is well-known that women socialize much more, including more conversing. They are probably much better at being social on the whole because of that. Meaning, women are much more likely to be charming and likable than men.
