K7 Computing Automation Developer- Trainee interview questions

I attended an interview process that started with an aptitude test, which I cleared successfully. The next stage was a technical interview, where I believe I performed quite well. However, after that, I received no communication from the company, no update, no feedback, not even a rejection email. Being ghosted after investing time and effort in the process felt unprofessional and disappointing. I hope the company improves its candidate communication moving forward.
