I got call from arcesium to take the interview and the process consist of 3 interviews when I asked then after clearing 3 round they said that one more round will happen. In the 4th interview the lady did not have much knowledge around time complexity for problem and then in last round i was out. The Hr also does not respond on time and had to followup myself after every round. Please dont waste the time of candidate if you dont want to hire. Worst interview experience.
