Altimetrik Senior Software Developer interview questions

I recently interviewed with Altimetrik for a Senior Software Engineer role, with the interview taking place at Samsung Electronics. While I appreciate the opportunity, the interview process was extremely disappointing and disrespectful of my time. I was scheduled for an 11:00 AM interview. I arrived promptly at 10:30 AM, well ahead of schedule. However, I was left waiting for nearly five hours, finally being called in around 5:00 PM. This is completely unacceptable and unprofessional. The interview itself consisted of basic DSA and React questions. While technical proficiency is important, the level of questions did not seem aligned with a Senior Software Engineer position. Despite the extremely long wait, I was informed that I had advanced to the L2 round. I was then made to wait another hour, only to be told that the second round would be conducted virtually at a later date. It has now been two weeks since this interview, and I have not received any communication from Altimetrik regarding the supposed next steps. This lack of follow-up is unprofessional and demonstrates a lack of respect for candidates
