Aquant Senior Manager - Strategy and Operations interview questions

The interviews themselves were good, but the HR/organization side was not responsive. I've needed to follow up with the HR person multiple times to get any response. After going through 5 rounds of interviews, I never got communication about the outcome or next steps. I followed up a week after the last round and then one month after that - no response. Followed-up for the third time 1.5 months after the last conversation and got the update that the company went with another candidate. Although the answer was ok, and I actually got offer from my top choice company, the experience was just unacceptable. After going through 5 rounds - it's fair to expect at least an update from HR or the team, especially after 3 follow-ups. really bad aftertaste
