dunnhumby Senior Developer interview questions

Interview Rounds: 1. Online Test 2. Telephonic Interview 3. Machine Test 4. F2F Interview 5. Another online test 6. F2F with UK counterpart It took a whole 1.5 months in all the process. After these 6 rounds, the HR was unresponsive for more than a month and after that, they simply dropped me an email to be available for another F2F the next day. They didn't even have the courtesy to call me for that. I simply became unresponsive myself as I didn't want to appear for any more round as they pay was also not very lucrative. The overall behaviour is very irresponsible and not what suits a good company. Quite disappointed.
