Carefully read about each required technology and prepare a detailed plan for learning it over the next three months. The plan should include:
- exact time frames,
- source of the knowledge,
- duration of the research,
- expected results.
For example, you do not know CSS and HTML5. Then you can say you ordered from
Amazon HTML5 and CSS3 All-in-One For Dummies 3rd Edition from Andy Harris. You will read it for 2 hours outside of work every day. You can also say that you use
w3schools.com and
stackoverflow. YouTube channels, official documentation, articles will also work.
This approach allows you to come up with a plan for self-development and also proves you as a goal-oriented person. Sometimes this is more important than knowing all the required technologies.
