Data Scientist job task requires many years of preparation to master many tasks.


I can tell myself I am not qualified or incompetent when I do not know the procedure on how to do the job or task but only for limited period of time. For example, I maybe not qualified or incompetent as a data scientist from 2 years up to 10 years. This is level 7 to 8 specific training preparation after the training I can take certification to prove my qualification or competency to do many known lists of specific to occupation tasks.

Software Technologies you are expected to know how to use from day 1 when you start your work.

I can tell myself I am not qualified or incompetent when I do not understand how to do the job or task but only for limited period of time. For example, I maybe not qualified or incompetent for less than 2 days. This is level 1 specific training preparation after the training I am now qualified or competent to do specific task.

I can tell myself I am not qualified or incompetent when I do not know the procedure on how to do the job or task but only for limited period of time. For example, I maybe not qualified or incompetent up to 1 month. This is level 2 specific training preparation after the training I am now certified as qualified or competent to do many known lists of specific to occupation tasks.

I can tell myself I am not qualified or incompetent when I cannot show, demonstrate, and explain how to do the job or task but only for limited period of time. For example, I maybe not qualified or incompetent over 1 month up to and including 3 months. This is level 3 specific training preparation after the training I am now certified as qualified or competent to do many known lists of specific to occupation tasks.

I can tell myself I am not qualified or incompetent when I cannot plan, direct, coordinate, integrate, review, approve, evaluate, negotiate, consult, prepare budget, propose new solution, identify root cause and so on to do the job specific to occupation task. This is level 8 specific training preparation after the training I am now certified or licensed to practice as qualifed or competent to do many known lists of specific to occupation tasks.

But since job or task are known repeatable, transferable, and teachable that requires specific time elapsed to acquire the knowledge, techniques, and skills to become certified, licensed, qualified, and competent. Therefore, my disqualification or incompetency will only last from hours, days, months, or years. Then I will become qualified and competent. So, I should apply for a job even if I don’t meet all the requirements.

If the job or task is not yet known as repeatable, transferable, and teachable. Therefore, all job candidates started with zero baseline for comparison. The hiring manager probably will base his/her hiring decision to known specified outcomes that the company expected to see as their measurement of success. The selected job candidate most likely has many foundational skills such as problem solving, communication, collaboration, persistence, and domain knowledge that will maximize the likelihood of delivering the specified outcome.
