Some tester friends asked me when they were looking for a job, or asked me online if there was an offer from an outsourcing company, should I go to an outsourcing company? Here I will talk about this issue based on my own experience and the situation of some friends around me. First of all, I have stayed in two outsourcing companies, and many friends around me work in outsourcing companies. So I just try to analyze this issue objectively, without any discrimination or belittling.
First, let me talk about the five characteristics of outsourcing companies:
First
Outsourcing companies are under a lot of pressure. As the name suggests, outsourcing is to do projects exclusively for Party A’s company, and charges are based on projects. Then, the more projects that need to be done per unit time, the better the performance of the company, so the only way to shorten the project cycle is through longer working hours. The most outrageous project evaluation time I ever encountered was 120 working days. As a result, the leaders shortened it to 15 days by holding meetings and discussions. As you can imagine, it is impossible to complete without overtime, and the so-called overtime wages can be imagined Normal hourly wages are not possible. And many companies only record overtime work after 7 or 8 pm. Some even only have meal allowances. They work overtime until midnight, and the money for a meal is spent.
second
There is only so much that outsourcing companies can learn. First of all, because they are all continuous projects, it is difficult to fine-tune a project, and the time does not allow it. Secondly, due to years of outsourcing projects, most companies have their own set of processes or have already packaged a set of frameworks. It is impossible and impossible to get in touch with the process of building a project step by step from scratch. In this way, in the long run, you may only know what you use, but not why you use it.
third
Outsourcing companies are unstable. Because outsourcing companies make a living by receiving projects, if the benefits are not good, outsourcing will have a release mechanism. That is, when the project in your hand is finished and there is no new project to assign to you, you may be released. At this time, you may only have a basic salary. I have met many brothers who were released and had to leave.
fourth
Outsourcing company wages are low. Don’t worry about this, because what is the significance of outsourcing? In most cases, it is too cost-effective to use the team of Party A’s company to complete some things. To put it bluntly, they need to do more technical things. Assign some relatively less important projects to outsourcing companies. If the cost of outsourcing is higher than that of Party A, then what is the point of finding outsourcing. Of course, there are also some start-up companies that seek outsourcing because they do not have a technical team.
fifth
There is some discrimination among employees of outsourcing companies in some HR circles, although it is rare to see recruitment notices stating that they do not want to outsource employees. But I did hear that some hrs did not like candidates from outsourcing companies, both openly and secretly. In fact, it's not just in the HR circle. Last year, the incident between a certain employee and a certain outsourced employee caused a lot of trouble on the Internet.
Summarize
Based on these points, I suggest that you try not to choose an outsourcing company if conditions permit. But it does not mean that outsourcing companies are useless, because outsourcing companies rely on receiving projects for a living. Usually, most of the costs can be basically recovered after project acceptance. Failures are also relatively rare.
Next, I want to share some of my generalizations and conclusions about technology over the years, and share my notes on the skills that a software test engineer needs to master. I hope it can help friends who are determined to go all the way on the road of technology. !
