Parallel Domain interview questions

My experience with this company's hiring process was disappointing. The process included a recruiter call, a hiring manager interview, and a system design assessment with a specific deadline. I invested significant time completing the assessment and submitted it before the deadline. After that, I was asked to provide my availability for the next round, which I promptly did. However, after submitting my availability, communication completely stopped. Despite multiple follow-ups over the past two weeks, I received no response from the recruiter regarding the status of my application. What I find most frustrating is that if the company had decided not to move forward with my candidacy, a simple rejection email would have been appreciated. Instead, after investing considerable time in the assessment process, I was left without any update or closure. Candidates invest their personal time preparing for interviews and completing assessments. The lack of communication after requesting that effort demonstrates a lack of respect for candidates' time. Based on my experience, I would encourage prospective candidates to carefully consider whether they want to invest significant time in this interview process.
