The interview process is simple, nothing to highlight actually. But be aware, Limestone Digital will waste your time, no updates, no feedback, nothing... And they hide behind the excuse that "the client has not decided anything yet". In my case almost three months passed since I was told that I passed the tech interview (they notified me right after the interview, like 1 or 2 hours after) and the client apparently still had not alloted a slot for an interview. I contacted them and told them I was not willing to continue in the process (which now I see is some kind of false process or something) and they apologized because the it was the client's fault. So, no ownership of responsibility, no interest in keeping you informed about what is going on. If anyone cares to read this, be very wary about this company.
