Two Sigma Developer interview questions

A long and drawn-out interview process. It began with an online technical interview. Next was a one-hour technical interview, then two one-hour back-to-back technical interviews. I scored perfect on all four of the technical interviews. Next was 3 back to back behavioral interviews. Did okay with these but felt that the behavioral questions seemed to be assessing one's communication skills in a personal setting rather than a technical setting. I then received a letter from HR indicating that I would have to wait a couple weeks for the next step in the prcoess. At this point I had multiple offers from top companies with deadlines approaching. No way I going to continue this long drawn-out process with Two Sigma and miss out on other great opportunities. Their process is too drawn out and I suspect they lose some great candidates.
