It& #39;s been over a year of us living in a global pandemic.

If you are showing up to an interview for a job that requires a little applied mathematics, the least you could do is be ready with the equation to go from R to the infection growth rate and the Laplace Transform.

It& #39;s hardly an original question. It& #39;s hardly difficult. And it& #39;s hardly esoteric.

It& #39;s straight forward undergrad level PDE problem. I don& #39;t expect you add fancy social variables there. Just get the basic equation.

R = e^(λT).

That& #39;s all.

It& #39;s very difficult to judge people in a remote working environment. At least for me. Because I usually depend on a lot of white boarding.

In the absence of that, standard problems are an interviewer& #39;s crutch. Use that and ace interviews, young people.
