EMAGIN Clean Technologies interview questions

The interview process initially seemed organized with a web based interview and then in-person interview with the data science lead. The interviewing panel was younger (early to mid 20s) and the data science lead did not seem to possess enough knowledge in her field. A case study was handed over to solve, post in person interview and asked to submit in a week. There was no response to the queries on the case and before and after submission, I had to follow up to get feedback on the submission. It seems the entire team was going through a very hectic schedule in meeting the needs of a newly acquired client and working over weekends on this. Finally, I was declined offer after another round of follow up. The entire process was very disorganized as they did not seem to value the time of the candidates. They did not even care to formally take a feedback after 3 rigorous rounds of interview. I would personally not suggest any candidate to apply for any openings in this start up.
