Very bad experience interviewing with QuillBot. 4 times in a row they have interviewed me, taken me to the final round of discussion and later rejected me without any proper reasoning. They make you do assignments, understand your thought process, take you to final rounds and reject you for irrelevant reasons. Sometimes, I feel they are always hiring 6 months of the year and have never been able to decide whom to hire. They themselves reach out, calling out as a previous good candidate but never able to move ahead. So, be cautious before you apply here.
