US Mission Intern Interview Experience: A Path to Positive Reviews
Intern Interview: One Side of the Story
To get the US group reviews offer for the job of back-end development engineer (Java), I went through a rigorous interview process. In this article, I’ll share my experience with the US group reviewed intern interview, from the initial phone call to the final positive review.
Two Faces of the Interview
My interview experience consisted of two parts: the first interview with the HR surface and the second interview with the department boss. Each part was designed to assess my skills and knowledge in a different way.
HR Surface: The Initial Interview
On May 12, at noon, I received a phone call from the US group side, inviting me to a telephone interview. The interviewer thought I was in Beijing, but I had just returned to Qingdao, so we agreed to conduct the phone interview. On May 13, the interviewer called to confirm the appointment time for the phone interview, which was scheduled for May 14 at 6:30 PM.
During the routine interview, I was asked to introduce myself, including my academic background and project experience. The interviewer then asked me a series of technical questions, including:
- The difference between HashMap and Hashtable, including the implementation mechanism underlying
- Java Optimization 8
- The difference between String and StringBuffer
- JVM memory model, including each region stored content
- JVM garbage collection algorithm
- JVM class loading mechanism, parent delegation model
- Two algorithms questions: finding a hundred repeated digits and determining whether there is a ring in a list
- Multithreading knowledge: synchronized keyword, Lock, and explaining the difference between them
- Common design patterns such as factory pattern
- Advantages and implementation mechanism of the thread pool
- Network basics: TCP three-way handshake, waving four times, three times is why the connection is established, and disconnect to four times?
- HTTP POST and GET differences and connections
- The difference between processes and threads
- Database knowledge, four characteristics of the transaction ACID
- The principle common index, the underlying data structure B + tree
Two Faces Interviewer: The Second Interview
On May 19, I received a second interview with a two-faces interviewer. The focus of this interview was on my internship experience, including my tasks, technical points, and greatest achievement. The interviewer also asked me about my personal attitudes and communication skills, as well as my MySQL knowledge.
HR Surface: The Final Interview
On May 30, HR received a phone call asking me to confirm my practice time. They issued an internship offer, and I was officially accepted as an intern at the US Mission.
Internship Experience
I started my internship on June 20 and was assigned to the development environment. I familiarized myself with the work environment and began working on tasks assigned by my leader. The group had a routine of opening daily for breakfast at half past ten, with lunch breaks at twelve, and starting work at six in the afternoon. We had a meal allowance of thirty dollars after eight pm, with a taxi reimbursement from work after half past nine.
US Mission: A Fast-Paced Rhythm
The US group had a fast-paced rhythm, with daily technology sharing and company-level sharing within the department. The boss encouraged us to listen to share and participate in the morning meeting every day. The US Mission also had a unique approach to technical management, where everyone was responsible for their own business and helped each other solve problems online.
Positive Review: The Final Interview
After two weeks of the positive interview process, I received an email from the US group HR, informing me that I had passed the interview and was offered a formal position. The positive review was based on my performance during the internship, and I was required to submit a formal offer, including salary and benefits, by the end of October.
Conclusion
My experience with the US group reviewed intern interview was a challenging but rewarding process. I learned a great deal about the company culture and the importance of communication and teamwork. I am grateful for the opportunity to have worked with the US Mission and look forward to my future career plans.
