IHS Markit Analyst interview questions

Got an invitation out of the blue to apply from linkedin, I sent in an application from the website and 2 days later I was sent an excel and a written assessment by email. I completed them and was invited for an interview at their London office. The interview was initially with the person who would potentially be my direct manager, and he asked me about my background, why I applied etc. We chatted back and forth about the job spec and the state of the industry for around half an hour before his colleague came in to chat with me in Spanish. After a few minutes of Spanish conversation, we came back to normal discussion about the job and the culture of the workplace. The whole process lasted about an hour and was thoroughly enjoyable.

Waited for almost 2 months to get the feedback. Called their hr numerous times but they didn't not get back to me or answer any of my questions. Very unprofessional handling interviewed candidates.
