check the coffee machine, general cleanliness of the office especially breakroom if they are clean and well stocked,look for notices on printers or washroom's that "xxxxx is not working & repairs has been notified". See if they have a gym,check the condition of office chairs,are they ergonomic ?. Ask about appraisal process and career path. If they dont answer well and the interviewer is not clear on that,it means an unhealthy org structure. Finally check on glassdoor and a wild card search on google with the email domain of the org,something interesting might come up.
