Sql Interview Question #3

The Screening Interview (Pros, Cons and Tips) – Types of Technical Interviews

You have two SQL tables! The first one is called employees and it contains the employee names, the unique employee ids and the department names of a company. Sample:

department_name

The second one is named salaries. It holds the same employee names and the same employee ids and the salaries for each employee. Sample:

salary

The company has 546 employees, so both tables have 546 rows.

Print every department where the average salary per employee is lower than $500!

Be Attentive To The Questions Asked

The initial screening interview if taken in the form of a telephonic interview will be a test of your attentiveness.

Why Do You Want To Work For Our Company

4 Things You Need to Know When Interviewing for a Tech ...

Employers want to hire people who are excited about their customers, product or service as they typically are loyal employees. Research your potential employer to understand their corporate mission, values statement, community involvement, customer base and product offering. This answer allows you to show your research and passion for the company.

Example:“I recently read an article about the Habitat for Humanity project your business led in the surrounding communities. I have volunteered with them in my town and really appreciate their hard work and dedication to helping those in need. While reading the article, I was excited that your corporate values align with my own. That actually is what led me to check your website for current job openings. I would love to join your team and be part of the effort to make a difference in the community through my work here.”

Why Should We Hire You

Remember, recruiters prefer to hire candidates with the ability to solve a problem and help in building the brand more.

Your job is to present yourself as the best candidate. So, when answering the screening interview question “Why should we hire you?” try matching your qualifications to the requirements of the job role and how these qualities will play out.

This answer requires you to exude confidence, so make sure to practice your answer.

Also, remember to not sound over-confident. You don’t want the recruiter to think that you are too full of yourself.

Meaningful Questions To Ask The Interviewer

Interviews are a two-way street. You should be learning about them just as much as theyre learning about you!

Asking thoughtful questions is also a good way to stand out in the interview. The age-old adage people dont remember what you say, but they remember how you made them feel is so true when it comes to interviews, says Refael . When a candidate keeps the flow going in a friendly conversation, instead of making me feel like I am conducting an interrogation, I will remember our brief time together fondly.

Of course, you should tailor your questions to the specific situation, but here are a few meaningful questions you can ask:

  • What do you like most about working here?
  • What frameworks, tools, tech stack, etc. does your company use?
  • Can you describe the development process here?
  • How do you test your code?
  • Does the company offer opportunities for professional development, training for engineers, etc.?
  • Whats the most challenging project youve worked on here?

The other upside: while youre listening to their answer, you get a little break from talking!

Practice Articulating Your Process

Lets assume its a given that youre already updating and practicing technical skills: language-learning, code-writing, bug-testing, and problem-solving. But are you practicing voice-to-voice communication?

Its one thing to know what you know in your head. Maybe you can build a webscraping application in Python that catalogs 30 years worth of Canadian hockey statistics in your sleep. Awesome. But if you arent able to thoughtfully and succinctly articulate this skill, youre not going to make it to the next round.

The only way to practice talking about what you know is to talk about what you know.

Now is the time to ask a favor from friends, classmates, or peers who have similar skills and technical knowledge. Have them dial you up or meet you in person to practice voice-to-voice question-and-answer conversations over technical information.

Keep in mind, one thing interviewers are listening for is an articulation of your thought process. Go ahead and think aloud, which demonstrates your comprehension and logic jumps while problem-solving.

*Lemons to lemonade tip: it may take several tries with real-life technical phone screenings to make the cut to an interview. This is normal and you can view each technical phone screening as an opportunity for more practice.

Onsite Vs Remoteshare Section

Typically, the large part of the interview process happens onsite, but this is changing as more companies build remote teams or wish to accommodate candidates who are not local. You can use many interview formats either in person or remotely this includes even live coding challenges. A companys resources and the candidates availability usually determine whether a particular part of the process will be conducted remotely or onsite.

Remote interviews have a few specific use cases:

  • Typically , remote interviews are concentrated earlier in the funnel and may include:

  • Online challenges and take-homes.

  • Phone screens, both general and technical.

  • Technical screening questions, questions where the candidate can code in the browser during a screen share, and light behavioral questions. Note that while you may encounter binary decision points or spikes in the signal during remote interviews, this is not a useful format for making more fine-grained decisions.

The Right Way To Read Resumes & Design Questions

Every job search starts with a resume or web profile whether it comes in as referral or through a proactive sourcing strategy. While current wisdom suggests that resumes arent all that important compared to what a candidate actually knows, Roseman argues theres a lot to be gained through careful review.

The things that most teams have the least experience in is how to read a resume, identify the areas worth probing, and determining how to probe into them.

While screening resumes, Roseman keeps an eye out for areas where he can push candidates. I always look for things where they have a measure of their success, especially if they make comparisons or use percentages. For example, “grew revenue by 50% or decreased downtime by 30%.”

This is how he develops most of his questions. You want to find out what somebody really did, as opposed to just being an observer or a participant, Roseman says. Even at the greatest companies, theres a gap between those who get the most stuff done and those who dont get much done. You need to try and figure that out during an interview.

As an example, here is a resume snippet Roseman recently received, Led a team of 3 engineers in creating massively scalable storage infrastructure used by various Google products. Roseman took note of this and during the interview, had the candidate whiteboard the infrastructure, and then highlight his main contribution, where Roseman could dig down and see if he really knew his stuff.

They Don’t Try To Show Perfection During The Phone Screen

How to ace your technical interviews

I always try to tell my candidates that I don’t expect perfection, using different words. Although perfection may happen – I see it about once a year – most candidates will not get the answers completely correct. They will forget some condition, have some syntax problem, provide a solution that is not optimal. That’s usually ok.

Trying to be perfect is likely to make candidates focus on the wrong things during the interview and get nervous if they can’t be perfect at that time, which will in turn prevent them from showing a lot of things that they’re perfectly good at.

Who Is An Interview

The person who does pre-employment screening is an experienced person who knows a lot about the niche they are hiring. Theyre usually IT professionals who can dig deeper into potential employee knowledge.

  • Technical interviews know what type of experience, knowledge, and personality the potential employee should have, so they will ask them a number of questions in order to see if youre the perfect fit for a company and a job.

For example, if a company wants to hire Java developer, the interview will ask candidates technical interview questions such as How does Garbage Collection prevent a Java application from going out of memory? or How is Java SE related to Java EE?.

In this article, Ill show you three SQL test exercises that, in my experience, are quite typical in data analyst job interviews.

Preparing For A Technical Interview

Practice Questions to Prepare for the Technical Interview

Technical interview preparation is key to being successful.

Candidates should not assume that they will know all of the answers just because they have a degree in the subject. In a technical interview, candidates are likely to be asked questions that:

  • Relate to specific knowledge about the companys technical activities
  • Relate to understanding the technical work required as part of the job
  • Relate to work completed as part of a degree course
  • Require candidates to solve actual technical problems that they might face in the job.

The best way to prepare is to first go through all of the details provided in relation to the job .

Brush up on any equations you would probably never use in the workplace, but that you had to learn when studying for your qualification.

Do as much research as possible into technical interviews job-advice websites often provide examples of questions you might be asked, as well as technical interview tips.

Practise, showing your methodology. You might be able to do 90 multiplied by 80 in your head, but for the purposes of the interview, practice reverting back a stage when you would have calculated:

9 x 8 = 7272 x 100 = 7,200

Its unlikely you will be asked a question you have seen before. As such, have a go at keeping your mind under control when you read a completely new question.

Try and replicate interview conditions as much as possible, and work on trying to keep a cool head so that you can digest the question and start crafting your answer.
