One reason employers ask difficult questions is to seek out important information about you. For example, employers might ask you to tell them about yourself. While it is difficult to provide a brief, eloquent summary of yourself, it is helpful context for employers to understand.
Another reason employers ask difficult interview questions is to learn about your thought processes. Lastly, employers might ask tough interview questions to gauge your experience level and comfort with difficult tasks.
This is more common in technical roles like computer programming or accounting. These questions should be answered to the best of your ability. When preparing for your interview, think about a few different scenarios of tough questions you may be asked depending on your industry. What critical feedback do you most often receive? Tell me about a time you overcame an obstacle. Employers ask this question to understand how you deal with difficulties.
You can use the STAR method when answering behavioral interview questions like this. Provide a brief summary of the situation, your role in the situation, the action you put into place to resolve the issue, and how the issue was resolved as a result.
A customer purchased a dress online and had it delivered to the store where it was accidentally purchased by another customer. Before calling the original buyer, I located the same dress at another location nearby. I ordered it to be pressed and delivered to her home the morning of prom with a gift card to thank her for her understanding. The customer immediately wrote us a five-star review on several review sites.
How do you handle stress?
You can answer this question by explaining how you typically respond with an example to support it. For example, I was working on a project with another team and we found there was duplicate work being done. By scheduling a weekly standup and keeping open lines of honest communication with our teams and managers, we pushed the project forward and ended up contributing to a significant company goal in a big way.
What have been your most positive and negative management experiences? Employers might ask you this question to understand what you like and dislike in certain management styles.
This might help them decide whether or not you would be a good fit under a certain manager. You should answer this question honestly and as tactfully as possible. My most recent manager was terrific at listening to my needs and helping me get the resources I needed to achieve my goals.
I thrive under managers who create a collaborative, trusting team environment. I understand how providing feedback on work or projects that could have been handled better is extremely valuable. This helps me to plan out my answer, give the best criticism possible and be less nervous. Why are you leaving your current position? This is valuable information for employers to understand. It helps them ensure the opening will be a better fit, make sure they can provide for what your previous employer did not or see if you might have contributed to a negative experience for both you and the employer.
Answer this question honestly, but refrain from providing too much personal or negative detail. What they usually do after you have finished coding is get you to write tests.
It is a huge plus if you write tests for your code even before they prompt you to do so. You should be emulating a debugger when stepping through your code. Jot down or tell them the values of certain variables as you walk the interviewer through the lines of code. If there are large duplicated chunks of code in your solution, restructure the code to show the interviewer that you value quality coding. Also, look out for places where you can do short-circuit evaluation.
Lastly, give the time and space complexities of your code, and explain why it is such. You can annotate chunks of your code with their various time and space complexities to demonstrate your understanding of the code. You can even provide the APIs of your chosen programming language. Explain any trade-offs in your current approach versus alternative approaches, possibly in terms of time and space.
If your interviewer is happy with the solution, the interview usually ends here. It is also common that the interviewer asks you extension questions, such as how you would handle the problem if the whole input is too large to fit into memory, or if the input arrives as a stream.
This is a common follow-up question at Google, where they care a lot about scale. The answer is usually a divide-and-conquer approach — perform distributed processing of the data and only read certain chunks of the input from disk into memory, write the output back to disk and combine them later. Practice with mock interviews The steps mentioned above can be rehearsed over and over again until you have fully internalized them and they become second nature to you.
A good way to practice is by partnering with a friend and taking turns to interview each other. A great resource for preparing for coding interviews is interviewing. This platform provides free and anonymous practice interviews with Google and Facebook engineers, which can lead to real jobs and internships.
By virtue of being anonymous during the interview, the inclusive interview process is unbiased and low risk. At the end of the interview, both the interviewer and interviewee can provide feedback to each other for the purpose of helping one another improve. Doing well in mock interviews will unlock the jobs page for candidates, and allow them to book interviews also anonymously with top companies like Uber, Lyft, Quora, Asana, and more.
For those who are new to coding interviews, a demo interview can be viewed on this site. Note that this site requires users to sign in. I have used interviewing. The experience was great. Aline Lerner , the CEO and co-founder of interviewing.

She has also published a number of coding interview-related articles on the interviewing. I recommend signing up as early as possible with interviewing. Practice interviewing anonymously with engineers from top companies! Another platform that allows you to practice coding interviews is Pramp. Where interviewing. Pramp pairs you up with another peer who is also a job seeker. The two of you take turns assuming the roles of interviewer and interviewee.
Pramp also prepares questions, and provides solutions and prompts to guide the interviewee. Because when I do interviews, I ask questions that are familiar to me. Also, many users do not have the experience of being an interviewer, and that can result in a horrible interview experience. In one instance, my matched peer took on the role of the interviewer but he did not have the correct understanding of the question and attempted to lead me down the wrong path to solve the question.
However, this is more of a problem of the candidate than the platform though. Go forth and conquer After doing a fair amount of questions on LeetCode and having enough practice doing mock interviews, go forth and put your new-found interviewing skills to the test. Apply to your favorite companies or, better still, get referrals from your friends working for those companies.
Referrals tend to get noticed earlier and have a faster response rate than applying without a referral. Good luck! Practical tips for coding questions This section dives deep into practical tips for specific topics of algorithms and data structures, which appear frequently in coding questions. Many algorithm questions involve techniques that can be applied to questions of a similar nature.
The more techniques you have in your arsenal, the greater your chances of passing the interview. For each topic, there is also a list of recommended questions, which is valuable for mastering the core concepts. Some of the questions are only available with a paid subscription to LeetCode, which in my opinion is absolutely worth the money if it lands you a job. General tips Always validate input first.
Check for inputs that are invalid, empty, negative, or different.
Advice for Conducting Interviews:
Never assume you are given the valid parameters. Alternatively, clarify with the interviewer whether you can assume valid input usually yes , which can save you time from writing code that does input validation. Are there any time and space complexities requirements or constraints? Check for off-by-one errors.

In languages where there are no automatic type coercion, check that concatenation of values are of the same type: int,str, and list. After you finish your code, use a few example inputs to test your solution.
Is the algorithm supposed to run multiple times, perhaps on a web server? If yes, the input can likely be pre-processed to improve the efficiency in each API call. Use a mix of functional and imperative programming paradigms: Write pure functions as often as possible. Use pure functions because they are easier to reason with and can help reduce bugs in your implementation.
Avoid mutating the parameters passed into your function, especially if they are passed by reference, unless you are sure of what you are doing. Achieve a balance between accuracy and efficiency.
Use the right amount of functional and imperative code where appropriate. Functional programming is usually expensive in terms of space complexity because of non-mutation and the repeated allocation of new objects.
On the other hand, imperative code is faster because you operate on existing objects. Avoid relying on mutating global variables. Global variables introduce state. Make sure that you do not accidentally mutate global variables, especially if you have to rely on them. Generally, to improve the speed of a program, we can choose to either use an appropriate data structure or algorithm, or to use more memory. Data structures are your weapons. Choosing the right weapon for the right battle is the key to victory.
Know the strengths of each data structure and the time complexity for its various operations. Data structures can be augmented to achieve efficient time complexity across different operations. For example, a HashMap can be used together with a doubly-linked list to achieve O 1 time complexity for both the get and put operation in an LRU cache.
HashMaps are probably the most commonly used data structure for algorithm questions. This has worked for me at times.
If you are cutting corners in your code, state that out loud to your interviewer, and explain to them what you would do outside of an interview setting no time constraints. For example, explain that you would write a regex to parse a string rather than using split , which does not cover all cases.
Sequence Notes Arrays and strings are considered sequences a string is a sequence of characters. There are tips for dealing with both arrays and strings, which will be covered here. Are there duplicate values in the sequence? Would they affect the answer? Check for sequence out of bounds. Be mindful about slicing or concatenating sequences in your code. Typically, slicing and concatenating sequences require O n time.
Use start and end indices to demarcate a subarray or substring where possible. Sometimes you traverse the sequence from the right side rather than from the left. Master the sliding window technique that applies to many substring or subarray problems. When you are given two sequences to process, it is common to have one index per sequence to traverse. For example, we use the same approach to merge two sorted arrays.
Corner Cases Sequence with 1 or 2 elements Sequence with repeated elements Array Notes Is the array sorted or partially sorted? If it is either, some form of binary search should be possible. This usually means that the interviewer is looking for a solution that is faster than O n. Can you sort the array? Sometimes sorting the array first may significantly simplify the problem.
Make sure that the order of array elements do not need to be preserved before attempting to sort it.Reg flags: If they were in a management position and didn't oversee the number of people you'd expect, this could be a red flag and could indicate an inflated title.
What were your responsibilities when you worked at job x? Tell me a little about yourself. Red flags: Candidates who are vague about what their responsibilities were, who didn't have the responsibilities that normally come with the job, or didn't have ones relevant to the job they're applying for.
Do you have any regrets? Explain why it is written as such, and what it is trying to achieve. Are there any time and space complexities requirements or constraints? Whether you're searching for your first job, changing careers, or looking for advancement in your current line of work, Job Interviews For Dummies shows you how to use your skills and experiences to your advantage and land that job.
