The city’s search for a full-time fire chief took a step backward this week. Because of a clerical error, the Civil Service Commission will conduct a second set of interviews with seven candidates for the position instead of moving forward with the three finalists selected earlier this month. According to the city attorney’s office, Columbus Human Resources Director Mike Oglevie sent a memo containing 13 of the 17 interview questions to six of the seven candidates prior to the June 6 interviews with the Civil Service Commission, leaving one candidate off the list of recipients.
