Jupiter Asset Management Data Science Traineeship interview questions

Applied and had to complete an online application form answering several questions 250 words each. The questions were reasonable and was emailed a few weeks after stating that I had progressed onto the next stage of the process. The HR assistant asked when I’d be free to discuss my application, after replying back the same day and the week I received no response. I called their number and emailed the company yet still didn’t hear anything back. Unprofessional to say the least.
