I was messaged via linkedin by a recruiter. I asked for a base salary, when she gave me a range I then became interested. She never actually bothered showing up to the phone screen.

Steer clear. Interviewers are constantly late. Started off with a phone screen by a recruiter followed by another thirty-minute call with the recruiter. Later moved to a one-on-one round, then a panel interview with multiple people which lasts around two hours. Interviewers ask all the same questions differently phrased! Before the final round must complete an assignment. Waste of time, energy, and effort. No need for so many rounds, can be cut in half.
