Steps like */10 line up with the clock, not with the moment you saved the crontab: */15 runs at :00, :15, :30 and :45 every hour. Cron has no way to say "15 minutes after the last run".
If a run can take longer than the gap between runs, stop runs overlapping with flock: */10 * * * * flock -n /tmp/job.lock /path/to/job.sh. A second copy then exits straight away instead of piling up.
Cron runs jobs with a minimal environment: use full paths, and send output to a log file (>> /var/log/job.log 2>&1) so errors are not lost.

Questions
How do I run a cron job every 10 minutes?
Run crontab -e and add: */10 * * * * /path/to/job.sh
How do I check the cron job ran?
Look in the job's own log if it writes one, or the system log: grep CRON /var/log/syslog on Debian and Ubuntu, or journalctl -u cron (cron.service is crond on RHEL).
What is the systemd timer equivalent of */10 * * * *?
OnCalendar=*:00/10 in a .timer unit. systemd timers can also catch up on missed runs with Persistent=true.
