Kortext Software Developer interview questions

My interview process with Kortext was frustrating due to repeated cancellations and a lack of communication. In total, interviewer canceled 4 scheduled interviews. In two of those cases, I received cancellation 5 minutes before the interview which left me waiting online at 6pm and 9pm for interviews that never took place. The recruiter also did not respond to my follow-up messages or propose any new times for rescheduling. It was lack of organization and consideration for candidates time.
