...you've got to take the process seriously, do your homework on candidates, and give ample time for success. Tom Walker of R1 Ventures has a great blog with cogent advice for startups and advice that any leader making a strategic hire should consider seriously.
In the exuberance of adding people, it’s common to see entrepreneurs make avoidable missteps. No hiring strategy is foolproof, but entrepreneurs can build the right team by avoiding these common mistakes: 1. Failing to achieve a cultural fit. 2. Not thoroughly verifying each potential hire’s background and expertise. 3. Hiring people who are functionally or personality-wise too much like you. 4. Underestimating how long it takes to find the right new hire, regardless of the job. If you move in a hurry, it’s guaranteed that you will make a mistake... Post jobs six to 12 months before you are ready to hire. 5. Waiting too long to correct a mistake.
