I came from math as well! For what it’s worth, I’ve found that even the brightest computer scientists and software engineers have a solemn respect for mathematics. Don’t worry about formal qualifications. This is an industry where the largest and most successful companies were started by college dropouts. It’s still very young and things are changing faster than academia can keep up. A willingness to learn and relearn is critical. My prep for big tech interviews basically boiled down to those algorithms classes, doing ~150 leetcode problems, slapping together a small junky android app, and perusing undergrad CS material on Wikipedia. To be honest, the first two are probably enough to get your foot in the door at the biggest companies.
