Grid Dynamics Senior Software Developer interview questions

Unless they are looking for a specific project, do not participate in a technical interview. I had 2 interviews for this company, twice they did not have a specific project in mind, just interviewing randomly. The first interview was one of the worst interviews in my life, the interviewer would ask some of the most weird and incredibly specific questions, after asking him if he ever used these he would say " I stumbled upon this a few weeks ago and wanted to see if you knew this ", bear in mind this is a senior developer with many years of experience. After 2 years I had another interview for this company, interview went awesome, answered basically all questions, (except again with a few very specific questions with again " I stumbled upon this a few weeks ago and wanted to see if you knew about it ", who does that ?). I was told I did not pass for senior but for middle ( bear in mind aside the very specific questions I answered everything, sometimes sluggish as I was stressed or misunderstood the question but still answered )."

The interview process had three phases, possibly four with the client’s tech test. Everything was respectful, and the technical interview stood out for being surprisingly friendly — which is rare nowadays. Unfortunately, after completing all stages successfully, they went silent. I was first told the role had been closed, then redirected to a PM who promised another opportunity, but they ghosted me afterwards.
