Just some thoughts I've come up with, feel free to comment or add.
1. Develop a clear goal - we change these frequently, can't accomplish anything without one though, doesn't mean making a lifetime commitment, it's frustrating when people ask me to help them and can't tell me clearly what it is they're looking to do
2. Develop an uncoventional way of obtaining that goal - The SJs succeed by going by the book, which always feels awkward to us, but the SJs will do tomorrow what we do today, and more importantly, we're typically more motivated blazing our own trail than following conventional advice, and the more technology advances, the less traditional methods work
An ENTP friend once found a job by e-mailing an opinion of a business to the company's CFO. It was highly opinionated and easily could've annoyed him as spam and philosophically wrong, but in the process he revealed he knew a ton about his company, which would not have happened if he had just passed along a resume to HR and followed all the rules as prescribed in the job description.
3. Use the ENTP advantage - we will learn more about a topic and communicate that knowledge better than anyone, even when using a resume play with the format so it lets the reader know this, even if it doesn't fit well with keyword scanners and modern tools
4. There are many SFJ human resources people hiring for ENTx executives.
This is why it can be so important to circumvent HR. They know MBTI, but are terrible at applying it. Can't tell you how many times I've seen HR screw up by hiring based on past experiences, not current preferences. HR people are often SFJs, often risk averse, and not likely to reach out to unconventional applicants the finance and marketing executives they work for would gladly hire after an interview.
In my experience, outside headhunters are less like to be SFJ, that business is heavy with ESFPs and ENFJs who want to make a buck and don't care about process as long as they get paid. They are much better allies to an ENTP, but will place you where you don't belong if your goals aren't clear.
5. If your process doesn't work, company might not be a fit anyway
The companies that are least likely to hire someone who doesn't follow a certain process are often the most bureaucratic, which is rarely good for an ENTP.
6. Quantify Your Output - certain number of contacts a day, certain number of calls whatever, we often fall short of the continuous effort needed to find a job, especially in the current market, and in my experience it's easier to stay on track if you measure your output, not your results
if results are not good, then adjust tactics, but don't stop targeting output levels, quantification also makes the process of rejection/no response seem far less personal
7. Repeat the Level of Output, not the Process - even if we have a process we like, we can easily tire after doing it 15-20 times, so mix it up to stay motivated
