Meltwater CSR-Customer Service Representative interview questions

I had 3 rounds, and the whole thing lasted for 1.5 month - Phone interview with the HR - Video interview with the HoS - Take home assignment - Pitch deck creation I had the initial call with the HR, and then the person set me up to having a video interview with the HoS next week. Everything seems fine, during the call with the HoS, he mentioned I should be getting the next step a take home test soon around next week. But the HR sent me an email said they'll give me an update next week asap, without mentioning the test(I sent them an email follow up said I will be waiting for an update, after that nothing has been exchange). And then 3 weeks has passed without any contact, suddenly they sent me an email and ask me to do a pitch deck and has to finish it within 72 hours within received the email. The HR did gave me a call and let me ask Qs about the test, however I do think they can do better in arranging the next step with the candidate, especially they've been ghosting. After completed the pitch deck, the day after they sent a canned email saying that thanks for the completion but they're not going to proceed. I sent them an email follow up and ask for interview feedbacks as I always do, but nothing. The whole interview process gave me a feeling that they just want you to do the pitch deck and use your insights in helping their business expansion. Even they might not want to proceed with your interview, they will still do let you do the deck.

(Pre-COVID experience) initial phone call with HR was very pleasant and made you feel like you made a real connection. Mostly behavioural questions, then she said how Meltwater has an unconventional hiring process and how the next step will be a group interview, thought it would be max 5 people in a panel style, but about 10 people showed up. All the other candidates were very nice, but all of us were very clueless. They provided charcuterie, food and drinks and had a few employees on site, seemed like rushing for a frat house rather than a work interview, office was really nice but I reckon it’s just a disguise covering up the ugly truth behind. All the employees were REALLY young, and the manager was well underdressed. They told you to go off and watch product demos in groups, and ask questions, then it breaks out to a social soirée type of activity where you go around and mingle with as many employees as you can and hope they’ll say good things about you at their meeting after. I’ve been through the rushing experience in university and the similarities are UNCANNY, very unprofessional experience. Glad I dodged a bullet after reading employee reviews.
