Does a 40-year-old June need to be able to do as much as possible?

Question

Career in IT

(epigraph) It seems to me, or is it really that yesterday's students are taken as juniors with only basic programming skills (I meet in vacancies)?

I'm 40 years old, set my sights on the profession of Android developer. And I think something like this: “I’m no longer a young energetic student (but smart). Why would an employer hire me as a junior if there are students? So, I need to know and be able to do a lot in order to surpass these students. Then I will become more attractive to employers in as a joon."

Made a to-do list:

Освоить обязательно:
Dagger 2
RxJava
Анимацию
Юнит- и интеграционное тестирование
Фреймы (сейчас юзаю Activity)
Gradle
Тонкости ConstraintLayout

Освоить желательно:
OkHttp
Retrofit
Architecture Compoments: Navigation, Paging etc.
Coordinator Layout
Motion Layout

Возможно:
Service providers
Виджеты

Изучить:

Распространённые алгоритмы

Уже умею (не просто умею, а использую в своём pet project):
Activity
Службы
Уведомления
Pending Intent-ы
LiveData
LifeCycle
ViewModel
Firebase
Room
Применяю шаблон MVP и пробую MVVM, стараясь понять, чем же он лучше.

But I'm thinking: Will I become too "cool"?
Can it turn out that "he knows how to be middle, but claims to be junior"?
In short, I'm afraid that if I learn too much, I'll scare off employers with my advancement.
For example, they can argue like this: “No, this one knows how to be a middle. But we won’t take him to a middle, because he has no experience. And it will be boring for him to work as a junior,” -?

Questions:

1) Is it possible that employers will start to argue like this:
"No, this one knows how to be a middle. But we won't take a middle, because he has no experience. And he will be bored as a junior"?

2) Is it necessary to strive to master the maximum number of skills, or is it not worth playing a smart guy, but wisely pretending to be a little fool? Where is the edge

Answer 1

In short, I'm afraid that if I learn too much, I'll scare off employers with my advancement .

lol
40 years old, but he thinks like an 18-year-old boy-maximalist
he will learn "too much"
you learn first
then come here
when you "learn too much" you will be at least 45 years old

But I'm thinking: Will I become too "cool"?

at the very first interview, a 25-30 year old dude with experience will grind you to powder and show your true place.
it's not an insult.
this is your future.

Answer 2

Do not learn to lope, without work experience you will always be a junior. Yes, and as the current is asked a little more complicated than the basics, you will immediately fail on any topic you choose

Answer 3

"thinking too much"
40-year-old job seekers have a problem more important than the problem of 'choosing who to position themselves', for example, a classic employer will not choose a 40-year-old junior at least because he will not be ready to hope that this employee will be able to learn something. Why take risks when it is easier and cheaper to take on an inexperienced beginner, since at least he can.
Yes, there are exceptions, and yesterday's student may simply be an uneducated idiot or a 50-year-old who successfully passes exams for the third tower (they told me about this), but the employer cannot know this in advance and simply operates with probabilities.
A 40-year-old is expected to have a lot of experience and knowledge, so if you choose the direction of self-improvement, then improve your skills in a particular area, and do it perfectly. (just in many it will be stupidly difficult to do)

Answer 4

Look for connections and acquaintances to arrange at least some work. And there already from this place and dance what to master. The days of reading books in the evenings and pet projects are gone forever. This is no longer a surprise to anyone. Now everyone needs commercial experience.

Answer 5

It is very desirable to master everything in practice.
First, try to purposefully study the material of one direction for several months.
Then come up with a project and dive into finishing it.
Google the information, try not to rush, but to figure out how everything works and works.
As soon as you finish this project, start a new one, more difficult, while continuing to study theory.
My opinion:
a. If the theory is not supported by practice (not only tasks in textbooks, courses), then everything disappears and becomes useless.
b. It is better to learn one thing well, for starters. And then move on to the next one.

Answer 6

As it is far-fetched, not a lot
