Interviews are a source of anxiety for most job-seekers.

From being late to a clammy handshake, there is plenty that can go wrong in those precious few minutes. But it is the thought of being stumped by an unexpected question that keeps even the most experienced professionals up at night.

Now job site Glassdoor has pulled together a list of the 20 toughest interview questions candidates faced over the last year - and the companies where they were asked. Microsoft, Tesla and American Express are among the global giants that left future employees squirming in their seats. 

However experts believe such head-scratchers are designed to reveal something about the candidate and don't always have a 'correct' answer. As David Whitby, of Glassdoor, explained: 'It not necessarily about getting the right answer, more how you cope under pressure.'

Here, FEMAIL reveals the top 20 fiendishly tricky questions - and offers an expert opinion on the best possible answer for each...

The Red Devils lost the UEFA Super Cup final in Skopje against Real Madrid 1-2. The Jose Mourinho’s players played very well, but Los Blancos were the better team.

In the very beginning of the game, Manchester United looked better than Real Madrid. However, the Zinedine Zidane’s players managed to take the initiative and created a lot of goal-scoring chances before the end of the first half. Firstly, they hit the bar after a corner kick. Eventually the midfielder Casemiro sent the ball into de Gea’s net in the 24th minute. The goal was very controversial, because it looked the midfielder was in an offside position.

Jose Mourinho tried a different approach in the second half, but Isco scored a nice goal after a one-two pass with Gareth Bale in the 52nd minute and probably decided the game. Just a few minutes later, the Welshman appeared on a good position in the box, but his shot reflected of the bar.

Romelu Lukaku should regret for the biggest miss in the game. The Belgian forward had the chance to find the net immediately after the second goal of Real Madrid, but his shot from several metres didn’t went into the net. Lukaku, then, scored from a similar position in the 62nd minute and brought United back in the game.

Maybe the biggest mistake of Mourinho was the decision to play Marcus Rashford. The youngster performed really bad. He missed in an one-on-one chance a few minutes after Lukaku’s goal. Then, Rashford took several free-kicks, which were more than terrible.

Cristiano Ronaldo went on the pitch for the last 7 minutes of the regular time, but the Portuguese starcouldn’t score against his former team. The forward had the chance to shoot from a free-kick in the added time, but his shot went wide.

The trophy is the 4th for Real Madrid in the history of Los Blancos. That was the 3rd lost final in the competition for Manchester United.

That planet is Venus ( Sao Kim)

The hottest planet in our solar system is Venus, even though it's much further from the Sun. 

Venus remains that same temperature no matter where you go on the planet. Average temperature is 462 degrees Celsius.
