At the age of 26, I changed my career from finance to software testing. After four years of precipitation, I have been a 25K Test Development Engineer

This article is definitely not feeding chicken soup , But tell you the real way to change your career . A little longer , Please take a closer look

Some people will go ashore easily .

Some people will struggle to get ashore .

Some people drown in the water .

I'm the one struggling to get ashore .

I used to work in Finance , Later, I changed my profession by myself and became a soft test programmer , Engaged in software testing 4 year , At present, I am deeply engaged in test and development

There happened to be several college students working in Internet companies , They are all engaged in IT Of technical work , And they all got a good salary, much higher than me ,“ I decided to change my career IT industry , At that time, it was all about money to change careers “, I thought the financial salary was too low , Not suitable for boys , I just want to change my career .

I've also seen a bit of development related content , In contrast, I think the work is harder than the test , Learning is also more difficult , I'm not a computer related major myself , I think software testing is more suitable for me . Later, in the process of learning , Find yourself interested in this area , So I persisted .

At that time, I thought it would cost 4-6 A month's time cost , In addition, I'm not sure about myself , After considering all aspects , I still adopted the way of self-study , I searched some resources on the Internet , Use your spare time to study every day , It took half a year , Successful entry . But learning efficiency is too low , Qualified friends can sign up for a training class to study .....

As the saying goes, men are afraid of entering the wrong line 、 Women are afraid of marrying the wrong man . stay 26 This golden age began to seek change , It's actually a very good choice . Back to the question itself , Many people still have a lot of confusion when they decide to enter this industry , Let me give you some practical advice ：【 At the end of the article, I share a wave of my learning route and supporting learning resources 】

One 、26 Is the software test suitable for changing careers at the age of ？

26 year Generally speaking, it means graduating from college or college 3 About years ago , Have certain working experience and experience , At the same time, some edges and corners are retained .25 It can only be said that your life has just started , The reason for this age level concern is that various Internet reports advocate everywhere 35 Age crisis , In fact, there will be crises in any industry , How to get through these so-called crises smoothly , The key point is whether you have relevant Core competitiveness .

stay 26 The age of , Be aware of the bottleneck and crisis of industry development and actively change the demand , In fact, it is very valuable , Don't be paralyzed by easy life , You need to keep your learning ability , Because the future is full of changes and opportunities .

Two 、26 How to change careers at the age of zero ？

I have some suggestions for changing careers on a zero basis , I hope it can help you change your career smoothly .

• Find a suitable learning material ： Can be in b Stand and find a material that you are interested in and can learn , There are a lot of online materials. Many children will find a lot of materials when they study by themselves , Think the more the better , It's not , Find a relatively complete material to read , Have a complete learning system , These I also have to sort out, friends in need can get at the end of the article
• Do more exercises to consolidate your knowledge : Most of the time, self learners will brush the interview questions first , I suggest more practice to consolidate the knowledge , This is very helpful to improve skills and technologies , Otherwise, it's easy to get into a misunderstanding, and you'll , A vicious circle of waste after practice .

3、 ... and 、 What kind of person is suitable for software testing ？

The threshold for software testing is low , The requirements of general enterprises for software test engineers are ： College degree or above ; There are not too many professional requirements ; Familiar with common techniques of software testing 、 Method 、 technological process , Familiar with automated testing （ It's hot at the moment ）; Have corresponding business knowledge ……

therefore , For many non computer professional zero foundation friends who want to switch to software testing , at present , This industry is very tolerant of people with non professional backgrounds , As long as you master the relevant knowledge and Technology , Have the ability to solve practical problems .

Four 、 Can you find a good job after studying ？

It's hard to find a job , The present situation is ： There are many employment opportunities in the first and second tier cities , Good job hunting , The third and fourth lines are not very good . secondly , Look at the personal segment , Pure functional testing is now saturated , It's hard to find a job , Pay back , But if the interface 、 performance 、 In terms of Automation , The job is easy to find , And the salary can easily exceed 10000 .
