What Should Our Team Be Doing Differently That Could Yield 10x Improvement

Meka Asonye leads the Startup & SMB sales org at Stripe, a group that advises venture-backed companies on their commerce, monetization and expansion strategies. Im looking for folks who have a bias for action and can think like an owner, he says. Can they think at the CEO level, beyond just the job theyre applying for?

Sometimes, this question surfaces some real gems. We’re actually considering piloting one of the ideas a recent candidate mentioned. I’ve also had interviews where people have mentioned things that we have seriously considered but scrapped for various reasons, says Asonye.

But when the answers are less than stellar, heres where candidates tend to go wrong:

Ambitions aren’t lofty enough. Oftentimes I hear ideas that are a 10% improvement, not 10X. The temptation can be to offer non-controversial, minor tweaks to process, says Asonye.

Cant think of any suggestions. This one is a big red flag for me, as I tend to see candidates in a second or third round interview, after the candidate has met with five to 10 people, says Asonye. They should be pretty well-versed in our company and product by then, so its often a sign that they havent done their homework.

To troubleshoot conversations that have stalled out, Asonye offers helpful footholds with these guiding questions:

Why might we be unable to raise our next round of financing?

Why would someone choose to work with our biggest competitor?

How Do You Prioritize When You Have So Many Tasks

Whats A Time You Disagreed With A Decision That Was Made At Work

The ideal anecdote here is one where you handled a disagreement professionally and learned something from the experience. Zhang recommends paying particular attention to how you start and end your response. To open, make a short statement to frame the rest of your answer, one that nods at the ultimate takeaway or the reason youre telling this story. For example: I learned early on in my professional career that its fine to disagree if you can back up your hunches with data. And to close strong, you can either give a one-sentence summary of your answer or talk briefly about how what you learned or gained from this experience would help you in the role youre interviewing for.

Possible Answer To Whats Your Management Style

Technical Interview Questions and Answers: Networks | Google IT Support Certificate

Management style is so hard to put your finger on, but I think in general a good manager gives clear directions and actually stays pretty hands-off, but is ready and available to jump in to offer guidance, expertise, and help when needed. I try my best to make that my management style. I also go out of my way to make sure I know when my team needs help. That means plenty of informal check-ins, both on the work theyre doing and on their general job satisfaction and mental well-being. I remember one project in particular at my most recent position that involved everyone working on a separate aspect of the product. This meant a lot of independent work for my team of seven people, but rather than bog everyone down with repetitive meetings to update me and everyone else on progress made, I created a project wiki that allowed us to communicate new information when necessary without disrupting another team members work. I then made it my job to make sure no one was ever stuck on a problem too long without a sounding board. Ultimately, despite the disparate project responsibilities, we ended up with a very cohesive product and, more importantly, a team that wasnt burnt out.

Tell Me About Your Ability To Work Under Pressure

Answer tips

You may say that you thrive under certain types of pressure. Give an example that relates to the type of position applied for.

Mention routine pressure you face, such as dealing with deadlines on a regular basis.

Try not to use an example where you created the pressure yourself, by waiting too long to start something, or by handling a task irresponsibly at the beginning. For example, working under pressure to meet a customers deadline could be a good example, but not if you had waited too long to start the project.

Answer samples

Pressure is actually a catalyst to my work. When there is an imperative deadline, I refocus my energy into my work which in fact, has helped me to produce some of my best works. I guess you can say I thrive under pressure.

What’s The Difference Between Quality Control Quality Assurance And Testing

An interviewer might ask this question to make sure you understand the differences between the testing and control processes. In your answer, briefly describe each process using simple language. Highlight the primary differences between each one to show your technical knowledge.

Example: Quality control involves looking for defects in a particular software application and providing suggestions to improve its quality. Quality assurance involves planning and defining how an organization can implement its quality control methods. Often, quality control involves the use of tools developed in quality assurance. Testing is the actual method for finding issues, or bugs, with the quality of the application. The testing process ensures the software meets standards and user requirements.

Explain How Can You Find Broken Links In A Page Using Selenium Webdriver

This is a tricky question which the interviewer might present to you. He can provide a situation wherein there are 20 links in a web page, and we have to verify which of those 20 links are working and how many are not working .

As you have to verify the working of every link, the workaround is that you need to send HTTP requests to all of the links on the web page and analyze the response. Whenever you use driver.get method to navigate to a URL, it will respond with a status of 200 OK. This indicates that the link is working and it has been obtained. Whereas any other status indicates that the link is broken.

Lets now understand how to do that.

First, we have to use the anchor tags < a> to determine the different hyperlinks on the web page. For every < a> tag, we can use the attribute href value to obtain the hyperlinks and then analyze the response received when used in driver.get method.
